I've got a 07 Mustang with a P-1SC-1 Procharger with a 4.13" pulley. Car starts up fine idles up around 1200-1500 rpms when cold and then drops down to about 1000 rpm. Every once in a while when I'm cruising in 1st or even 2nd gear and put in neutral rpms will jump up between 1500-2000 rpms. I have to put it in gear and then back in neutral and it will idle back down. Anyone with prochargers experience this?
List of mods are P-1SC-1 Procharger w/ 4.13" pulley (boost ?), 39lb injectors, diablosport mafia programmer, and full exhaust.

I would contact the tuner and see if they can correct that

I purchased the car after the tune was already done. Do tunes ever need to be re-tuned?

I agree I dont think its your blower, You can always tune a car back to stock and then enter a tune again, I would go with an SCT. AmericanMuscle.com has them for about $450 but they are unlimited tunes if you up grade your car again just send it back tell them what you have done and they will send it back to you with a new tune. you might want to see if the throttle is sticking, Just a guess

my paxton blown 2v does the same thing when im stopped and in neutral at a stop light. the idle hangs at like 1500 rpm for a few seconds then idles back does to 850 rpm. my car isnt tuned fully though, so it may just be a tuning issue because i replacedd my IAC valve with a new one and it did nothing for me.

Mine has actually jumped up to 3000 rpms! I've read the iac restrictor plate mod should fix it. Just not sure how it would work on a procharged car.

the only problem with American Muscle is they use BAMA chips...And Bama will not make a tune for Procharger. Get a real tune on a Dyno...its the only way to get a strong running Safe tune.
