I just got finished installing custom 2.75 intercooler piping with a blitz bov and I replaced the factory metal hoses that used to run along the 3000 pipe with just straight hose. I go to start it up and it runs great until it starts to warm up and then it will surge from 500-750 rpm. It sounds like the problem everybody has here when they talk about idle surge and they try to remedy it by replacing the ISC and TPS but this stuff was working fine before the install so I wouldn't think that that would be my problem. Do I need to do an ecu reset since the engine is breathing better now? Or is there some fancy thing that needs to be done after a piping upgrade?
