Just figured I'd put my experience this weekend out there. I pulled my Procharger system off and installed it on my boy's '05 this past weekend. My car was running great at 11 psi, no problems at all at 9k miles. His car has almost 30k miles on it and ran perfect before the install. After I was done the car wouldn't idle even after setting the idle up higher with the Predator. Got up on Sunday morning and decided to pull his throttle body and maf sensor off for a cleaning. Problem solved. On a newer car I wouldn't think it's necessary, but he has almost 30k miles
