12 WRX stage 2 loss of power
I have a 12 WRX with Invidia catted downpipe, cat back, aem cai, GFB blow off valve and Cobb Accessport Stage 2 lwg map. It's been almost a week since installing the DP and catback and I'm noticing a notable loss of power. When I get on the gas around 3k RPM, the boost just sounds loud and like its spooling a lot louder than normal. During that time I feel like a have no power. It doesn't put you back in the seat like it used to. On the Accessport I've been watching the boost and it still boosts around target boost and eventually see it go to 24, 23 psi. I've also gotten wastegate solenoid CEL once before the exhaust install and once since the install. Car seems fine around normal driving below 3k rpm but anything higher and it definatly doesnt feel right. Anyone have any ideas? I've been looking and seeing info about IC to throttle body clamps could be loose or blown and other things about waste gate up pipe might could be bad. Another noticeable issue is the car seems to backfire a whole lot more when shifting or getting of the gas. If anyone has any good info please your advice is needed. Don't really feel like putting everything back to stock and taking to dealer but I'll do so if that's what it takes.
