With countless hours of development on the dyno, street, track and drag strip, MAX CAR Performance can optimize your car to work with a full race exhaust and other engine modifications. From the factory, the engineers deliver the car to meet strict emissions requirements. We make power and increase throttle response by adjusting ignition timing, where applicable cam timing, fuel calibration, and adjusting hidden torque limiters.

We can increase rev limit and speed limit for motorsport use, perform diesel tuning and fuel economy tuning, or add features to your car not originally offered on your model. MAX Car Performance can also cater to your boats, jet skis, industrial and agricultural vehicles.

We pride ourselves on the services we offer. Each vehicle is tested, tuned, and re-tested on location in Brookfield, CT using our AWD Superflow Dyno. Each tune is custom built for your car by an experienced tuning specialist.

All ECU tunes include a dyno run before and after tuning.
