Dyno Tuning

Dyno Tuning is a process where the air/fuel ration is adjusted for each throttle position.  This process optimizes your power output, throttle response, gas mileage, and extends the life of your engine.  It is necessary if any sort of work on the engine or exhaust system has been performed.

General Diagnosis

Having runability or start up issues? We offer a complete computer diagnosis and can often find the issue when other shops have failed.  It is a point of pride that we will not try to sell you fixes for things that are not broken—if it is a simple fix, we will let you know.  There may be times that the cases of an engine need to be split in order to have a complete diagnosis, in that case general labor rates will apply.

Computer Diagnosis -- $100
