Installed Jet PCM Stage 2, at first my truck ran fine, but then I accelerated, my truck would bog down, and got worse the more driving, eventually the Service Engine came on. I used rated octane and had modified engine. I removed the Jet PCM Stage 2 and my truck ran fine, I contacted JET support, I paid to deliver it so JET can diagnose the Jet PCM Stage 2. I should be hearing from JET soon, but not to happy with theJet PCM Stage 2 performance. Best thing to do is not to purchase its a 50/50 chance it may or may not work with your vehicle even if there is nothing wrong with the Jet PCM Stage 2 module.

jet performance module.

This is my third performance chip. the others had miles of wire to hook up and did not give me a real pick up feeling. But the JET PERFORMANCE MODULE was simple to snap in place no wires to run. I just ordered the 180 thermostat. Good product does what it was made to do.

I was very scared at first, the module is made of plastic and trying to secure it into the ECM was nerve crunching at the thought of snapping the plastic. After a hard start, the module adjusted the factory settings and damn, I was off. At an average I dropped off a second and a half on my 0-60, haven't tried the 1/4 Mile yet. I'm interested to see. Any Fuel Injected vehicles NEED this chip!
