Engine Calibration / Tuning
Engine Calibration, Custom Dyno Tuning and Race Support in Lewiston, Maine
We offer two kinds of tuning service for racing and competition vehicles and classics: custom calibration on our Dynocom AWD chassis dyno in Lewiston, and on site support at the track, rally stage, drag strip or your local dyno. Our owner is a professional motorsports engine calibrator and Holley expert, and every calibration is built around your goals and the safe limits of your combination.
Custom dyno tuning
We perform a full ECU calibration on our Dynocom AWD dyno using professional tuning tools, software and sensors, so your engine is calibrated to meet your goals and its maximum safe capability.
We tune the projects we build in house, and we can tune your project once it is pulled together. Let us help you get your build across the finish line.
On site support
We can bring our skills to the track, rally, drags or even your local dyno. We travel to support racing teams in the US and abroad.
Book our tuning staff for your next event and we will plan the support around your schedule.
Major supported tuning platforms
We support a wide range of aftermarket standalone engine management systems and factory OEM ECUs, offering custom calibration, diagnostics and chassis dyno tuning for supported applications, and many more platforms than listed here.

Emissions policy
We require that cars we tune are 50 state Federal/EPA emissions legal, including meeting any further emissions requirements of the state the vehicle is registered in. Cars that participate exclusively in motorsport competition (trailered, not registered) may be exempt from this requirement, although we may require that the car has a catalytic converter.
