Welcome to Custom PCM Tuning
Northern Arizona's premier custom PCM tuning service for '97+ GM cars & GM trucks
The P.C.M. (Powertrain Control Module) is the on-board computer of your vehicle that literally controls every single aspect of your engine, transmission & emission control devices. Performance bolt on's are just part of the power equation. A Custom PCM tune will surpass your performance goals and will truly wake up your vehicle.Custom In-Person PCM Tuning: $175.00
Custom PCM Dyno Tune: $350.00
What you can expect from a custom tuned PCM:
A more efficiently operating drivetrain will not only yeild faster acceleration, more power and more torque but during day to day driving, cruising and highway travel you will also gain MPG. You'll notice you'll use less throttle to not only maintain speed but to also get up to speed.
Because we also tune the transmission control tables as well as engine fueling & ignition timing we reduce slippage and friction in the transmission, thus reducing heat and extending the life of your transmission.
