2018 PCP Scat Pack w/dynamics
Hey guys, so I installed kooks LT headers w/ catless mids recently and got it tuned. Ever since it got tuned, I’ve noticed cold and warm starts are a bit rough. Cold starts will have large rpm dips (+-500), so it’ll sound like it’s about to die, then rev up. Sometimes on warm starts, the rpms will start very low, almost like it’s just weak. Before the tune, it just always fired right up. Like it roars to life, and slowly idles down. Does anyone know what might be going on? All temps are fine, no lights are on, and the car drives just fine. But these startups worry me a bit. Does anyone know what might be going on? My tuner suggested it’s probably a mechanical issue.
