testing & tuning
The roller on our dynamometer is rounded to within 0.00001 of an inch. This degree of precision, paired with our Timken bearing system, eliminates the false torque and speed spikes that can plague other dynos. Our dyno consistently produces valid replicable results, so our expert technicians can tune with pinpoint accuracy.
Improve performance and fuel efficiency
Our custom built dyno monitors your engine’s response to repeated passes that simulate real-road conditions. With each pass, we electronically fine-tune your engine (or adjust the carb, ignition timing, jetting & AFR) until we see an even torque curve with smooth shift points. By the time we’re done, you will realize an overall gain in torque and horsepower and a noticeable improvement in throttle response and driveability right through to the redline! We will also adjust your air-to-fuel ratio to optimize the rate of fuel combustion through each piston stroke. With this optimized combustion, your vehicle will be more fuel efficient than ever!*
*While dyno tuning improves fuel efficiency, many other factors such as tire pressure, driver behaviour, load-weight, etc, have an impact on fuel consumption.
Improve factory settings
The power parameters of new stock vehicles are set for generic driving conditions, decent fuel economy, adequate acceleration, and to meet specific marketing targets. They are rarely optimized for the performance they’re capable of, or for any specific application, or for your unique driving patterns. At International Dyno Authority we custom tune to your specific needs. Whether it’s highway driving, or city driving, or towing a trailer, or more punch and horsepower, our experienced professionals will tune your car, truck, ATV, or bike until it is running at peak performance.
WILL A TUNE VOID MY WARRANTY?
This is one of the most commonly asked and debated questions on forums. Given all the debate on this topic, we cannot give you a definite “yes” or “no” answer.
However, we can tell you this, from our own experience.
- Over half of the chassis dyno tunings that we do are on late-model vehicles that are still under warranty.
- We have NEVER had a customer come back and tell us they had a warranty issue.
- Several Ottawa area dealers have even sent new car owners to us for tuning when they could not meet the customer’s expectations.
We do ALL of our chassis dyno tuning within OEM specs. This helps reduce the risk of any potential warranty issues and it also reduces the risk that you will run into any engine problems as a result of tuning. We’ve had numerous vehicles on our chassis dyno, which had aftermarket tunes installed that were well outside of factory specs. On more than one occasion, we’ve seen these improper tunes cause cracked manifolds, leaking valve cover gaskets, scored cylinder walls, and detonation. Staying within OEM specs does not result in underperformance. There is no need to exceed their specification range. Manufacturers tune new vehicles for generic driving conditions and leave plenty of power on the table for us to find.

Excellent service and very knowledgeable! Definitely a return customer here!”
Tuning after Performance upgrades
Just like with ECU tuning, tuning a carbureted vehicle improves responsiveness, power, and fuel efficiency. Tuning is done in much the same manner; however, instead of using a computer to change the parameters, engine components are adjusted and fine-tuned by hand using timing lights, carb gauges, and jetting kits.
If you’ve installed a new air intake system or invested in a high-end carburettor like a Holley or Edelbrock, you won’t tap into their full potential until you have the engine’s AFR and timing adjusted. Make your performance investment pay off by dyno testing and tuning your engine to ensure proper aspiration for the best possible torque and horsepower.
Break-in is the most critical time in a rebuilt engine’s life. Performing the initial shakedown of your rebuild on the dyno is a great way to ensure future performance and engine life. Because we calibrate the engine load, you can be assured that all the rings will be tightly seated and that your cam lobes will be properly broken-in. And, after doing the break-in, we can proceed directly to tuning for power!
