GM LS DYNO TUNING $599& up   (Full Dyno Tune by 17 yr + Experienced Tuner)
 Computer programming  and dyno tuning  is one of the best modification to do to your car. Proper tuning can not only make your car more powerful, but also make it run more efficiently. This is available for stock vehicles, simple bolt-ons, highly modified engines and forced induction applications.
First, we connect our wide band sensor and VCM Suite software to obtain data from your vehicle to see check the efficiency and responsiveness. We then program your vehicles computer with a new program that helps to unlock the potential of your engine, we make adjustments for your shift points, torque management, shift time, rpm limits, traction control, cooling fan controls, skip shift and much more.
We then edit the PCM for additional power and torque by customizing hundreds of tables inside your engine’s computer to get the air fuel ratio and timing tables dialed in. Because every vehicle is different, 21CMC programs the vehicle for the modifications that are on the car and not some generic program that worked for someone elses car. The results from the programming changes are then measured at the rear wheels on our DynoJet Dynamometer. You will get a printed report with Horsepower, Torque and Air-Fuel Readings along with suggestions for upgrading the performance of your vehicle
              Special Pricing includes most GM LS Powered Vehicles
