We are providers of the highest quality tuning, performance packages and products to get the most of your late model GM car or truck.

At CJTunes we have one primary goal, extract as much reliable HP as possible while increasing fuel economy and improving driveabilty. This is achieved by making changes to your engine control module in order to increase efficiency. We also make many other changes including shift speed and pressure, torque management reduction or elimination, engine speed and top speed limiters, skip shift, etc. Since every car is tuned individually we can make the adjustments you want and get the results that you desire.
