I would really appreciate any imput/help if you don't mind. My car has been running on wastegate pressure for a while and I currently installed the Cobb3 port thinking that my solenoid was bad. I have the Accessport and a tune from RRE for the 3 port and it is still peaking at 12 PSI. I purchased a new MAF becuase I was getting the codes p0103 and p0113 and still no luck. The MAF voltage is staying at 5 so I figure it is getting power but too much power. My car is essentially not using the MAF at all. could this be a bad ground, or battery going dead, or alternator. Or even the plug to the MAF is bad. It has an AMS intake and UICP but it was doing this before I installed them. Any help would be much appreciated.
