dyno tuning

Fleet vehicles tend to operate within defined geographical limits. When an engine is properly tuned to its routine road conditions and driving style, you will benefit by requiring fewer repairs and an improvement in fuel efficiency of at least 10%.

Save on fuel & repair costs

dyno tuning is not just for performance vehicles

New vehicles leave the factory with their engine’s tuned to generic driving conditions to account for a wide range of driving environments, driving patterns, and types of terrain (hilly, flat, mountains, etc.). But, most fleet vehicle’s operate day-after-day within similar driving parameters. While some localities are fairly level with moderate temperatures, other fleets operate in hilly or even mountainous regions with a more severe climate.  For example, a fleet vehicle in Ottawa would be operating under very different conditions from one operating in Vancouver, or Manitoba, or Halifax. By tuning your fleet, specific to your location and application, you can improve performance, reduce repair expenses, and improve fuel efficiency.

What demands are you putting on your fleet?

Taxis may spend a good deal of time alternating between idling and driving in heavy traffic, while delivery vehicles may also operate in city traffic but spend less time idling. Other fleet vehicles will spend most of their time running at highway speed between major cities or to rural areas. Our custom-built dynamometer is capable enough to handle everything from a Smart Car to a 14L tractor-trailer!

If you’re fleet is routinely carrying heavy loads or towing trailers, we can adjust your tuning to deliver the torque needed for safe hauling. By increasing engine torque, your fleet vehicles will be more responsive to throttle which can result in safer operation and the need for fewer repairs to major drivetrain components.

The benefits of dyno tuning your fleet

Fewer repairs

When an engine is properly tuned to the road conditions and driving style it is routinely subjected to, transmissions will shift smoother between gears and less frequently. As a result, the life of your entire drivetrain will be extended, and you will have fewer repair costs.

Tuning will also help prevent a common problem with ageing fleet vehicles. Engine knock. Prolonged. Engine knock. Prolonged engine knock can cause serious damage to an engine. Tuning helps prevent these costly repairs by ensuring that your fuel, air, and ignition timing are properly balanced.

Heat and friction are the primary enemies of engines. Engine heat degrades your engine oil which leads to increased friction that wears out piston rings, push-rods, cylinders, crankshaft bushings, and many other vital (and expensive) components.

RPM & speed limiters

Every fleet has at least one heavy footed driver. Racing an engine can result in added repair & maintenance costs and can shorten engine life. Excessive speed is dangerous to everyone on the road and a liability to your company. We can help by limiting both the highest RPM and speed the engine will reach.

Multiple Tuning Options

Hauling tools in the summer and plowing snow in the winter?

These two scenarios require very different responses from a vehicle’s drivetrain.  Some fleet vehicles serve dual-duty depending on the season. Our solution is to provide two separate custom tunes that are easily installed via a hand-held ECU programmer.


improved fuel efficiency

And, perhaps most importantly, your fleet will enjoy improved fuel efficiency. At a minimum, you can expect an improvement in fuel efficiency of 10% a year.

So how does dyno tuning improve fuel efficiency?

First, when properly tuned a vehicle’s torque curve is optimized to be more responsive to driver input. This means that your drivers will not have to press as hard on the accelerator (flooding the engine with gasoline/diesel fuel) from a stop sign or traffic signal, or when passing on the highway.

Second, when the proper combination of air, fuel, and spark-timing is delivered to the engine’s cylinders, combustion is more efficient, and excess engine heat is reduced. As mentioned above, excessive engine heat causes premature wear on engine components. Wear and temperature also have an impact on fuel economy.

Worn parts due to friction can cause havoc with gas mileage and emissions since the engine is pushed to work harder. Wear on the engine’s vehicle is a primary known cause of less efficient burning of fuel.

Brought my Merkur to get tuned after being parked for 4 years, during that time it got a built motor, transmission and turbo upgrade, Marc, Wally and Chris all did a spectacular job, even when scratching there heads for a couple issues, they kept on having a positive attitude and even tried to teach me a few things and show how the process is done, these guys are definitly beyond the definition of professional and will take care of your car and you, I completely recommend bringing your car, bike, anything with a motor and these guys will figure it out and will help make safe reliable power. Even gave the Merkur a plug in his Facebook Livestream!! If you want to see what these guys do check them out of facebook or give them a call, these guys have your back.

The best dyno shop in Ottawa ! They treat you like family. Very professional and knowledgeable. I had my 5th Gen Camaro SS tuned by Marc and Wally and left smiling from ear to ear. The car runs super great and I have absolutely no complaints. Marc explained everything clearly and Wally did his magic, they got the beast out of it ! 75HP increase and over 100TQ at the wheels. It feels and drives like a new car on steroids. I would highly recommend this place for your tuning needs. Thanks guys 👍

Marc and Wally are great at what they do! It's a real pleasure to work with them. There's no pretense or posturing here just good honest HOT ROD experience. Marc answers the emails you send..good communication no flakiness like so called other tuners or experts...They were able to pull about 60 extra HP out of my 440 Charger. As well they had me back for a small adjustment I wanted done and Wally diagnosed the problem in about 3 minutes and tweaked the program on my MSD EFI and POW!!! Throttle response I was hoping for...wonderful....

Came in to get my axle and tire size recalibrated. Easy fix, but why stop there?.. you are at a Dyno shop! Woke my truck up from a 20 year nap. Less fuel, more power, and you wouldnt know my short box chev is a V6. The guys are great to deal with, very knowledgable, and talk honestly. The guy that left before me said "You will love this". 60s guy in a 60s muscle car with a smile bigger than a kid with candy. He wasn't wrong.

International is Best dyno place hands down. I went to RSP Motorsports in London which was a big mistake. They destroyed my computer and made me pay for it. Truck never ran good after they touched it. I called Mark and Wally and they took care of me and went out of there way to make sure my truck ran the best it could. Fantastic guys to deal with. Don’t go anywhere else period!!!

When considering tuning services for your vehicle, I highly recommend International Dyno Authority in Ottawa. Their facility is immaculate, and the team, particularly Marc and Wally, stand out as experts in their field. Not only do they provide a friendly and welcoming environment, but they also offer honest and transparent feedback about your build, steering clear of false promises. Throughout the tuning process, they take the time to guide you step by step, making gradual adjustments to witness your engine's remarkable performance improvements. Having visited them multiple times, I can attest to the consistently outstanding experiences I've had. Whether you seek a baseline dyno to assess your vehicle's current performance or wish to achieve significant gains through tuning, International Dyno Authority and the expertise of Marc and Wally are unparalleled. Moreover, on-site amenities, such as Joe's canteen, add to the overall positive experience and it is second to none!

These guys are top notch. This was my second vehicle tuned by Mark and Wally. I've done many mods to my Explorer ST and they made them all come together. My Explorer is a monster now but yet still tame enough to be a daily. Also i went to the dealer to have some unrelated work done and they ended up doing a update on my computer without my knowledge which ended up wiping oit my tune but Mark and Wally took care of me and were able to reload it back on no charge. I thought that was very commendable of them. Would highly recommend them for your tune. Thanks again guys for the amazing service. Cheers!! Chris

I wanted to take a minute for this overdue feedback to express how grateful I am for the work that Wally and Marc did on my Cadillac CTS V. They saved my car, which I thought it was a lost cause. After another tuning garage from Calabogie worked on my car and almost ruined it- I sought out help from Marc and Wally, I am very grateful for them saving my car. Their expertise is incredible. I also had my Ford F350 tuned with them and it's awesome. Thanks guys for the great work! I certainly recommend International Dyno.

Top notch service and super easy to deal with. I recently had my EcoDiesel tuned after putting in a pedal commander that just made it more jerky and hunting for gears whilst giving me worse gas mileage. This tune smoothed everything out not just engine but transmission tune as well……and has made it even better on gas while having more HP. I can’t thank Mark and James enough:)

I couldn't be more thrilled with the results. With just a few hours of work, Wally was able to extract over 100WHP from my 2004 Z06 (low-mileage w/bolt-ons). The improvement in performance is remarkable and speaks volumes about Wally's skill and proficiency as a tuner. Furthermore, I'd like to extend my appreciation to everyone else involved for the efficiency and professionalism demonstrated in setting up and breaking down everything once the work was complete. The team's commitment to excellence is truly commendable. The investment made in Wally's tuning services was worth every penny, and I am thoroughly impressed with the outcome. My Z06 now performs better than ever, thanks to Wally and the entire team at International Dyno Authority.
My Opinion
11:48 17 Apr 24
What a great experience having my car properly tuned these guys knows what they’re doing. I purchased a used Ford Mustang with some modifications. Then I added some modifications of my own like long tube headers. I showed up for my appointment and right away. They were asking if I had any engine lights on. From adding the long tube headers I told him no I have no engine lights. Everything’s running fine. They set my vehicle and they proceeded to tune my vehicle within the first five minutes of them checking my vehicle. They found that The previous person had that turned the car shut off all the engine lights that’s why they were surprised that there wasn’t an engine light on. If I didn’t bring my vehicle to have it tuned properly by professionals I could’ve ruined my car engine lights are there for a reason no one likes to see them , but they sure can save your car or something does happen needless to say, after everything said and done, I had a 230hp gain of horsepower I just want to thank the staff so much for taking care of my vehicle like it was one of their own. What a great place to have your car professionally tuned.

Thanks to Marc and Wally for this amazing experience. I brought my 2021 Ram 1500 5.7 to have it tuned. After Wally made a few base passes now it was time to start fine tuning. After several passes Wally was able to get out of my truck +108 WTQ & +80 WHP from my best base pass. That is quite impressive!, I'm not driving the same truck. I recommend the experience to anyone that wants better power but also better fuel economy. Thanks guys for your professionalism. 😀

Marc, James and Moe did an amazing job getting my 2010 Acura TL tuned. They are all knowledgeable and explained everything throughout the dyno session. I even forgot to tell Moe about a modification I did, which resulted in a check engine light. He said no problem just come over to his house and he got that all squared away. Will definitely be coming back if I need to tune any cars in the future! I even added a photo to show just how much power they were able to squeeze out of the car!

I won a raffle at International Dyno Authority on June 9, 2024 for my 2010 Mustang GT convertible on their Mustang Dyno Day! The technicians, Mark and Wally, were very professional and did the job perfectly! They took their time and made several passes to make sure that the tune was the best for my Mustang. Wally & I then went for a test run, and I noticed a difference in the pick up and the shifting of the gears. I would highly recommend them to do your tune!
