A PSI PCM is a great addition to your PSI Harness as they are tuned specifically for your set up!

With over 15 years of tuning experience, we start by ensuring your PCM has the correct operating system for your Engine & Transmission combination

PSI will calibrate the PCM for the correct MAF, Injector Size, Throttle Body type, Tire Size & Gear Ratio as well as shut off the VATS (Vehicle Anti-Theft System).

Your vehicle will run as it should when you turn the key.

We do not offer custom tuning for modified engines, but we do leave the PCM unlocked so they can be tuned by a local tuner.
