I have an 06 WRX with 26,000 miles and i have a COBB catted turboback, COBB intake, and accessport flashed to stage 2 91 oct. Me and my friend were cruisin around and i pulled out my accessport to see what kind of boost i was pushing. In 3rd and 4th gear the highest it would go is 13.2 but it would hold until i let off the gas. Now i have an appointment at COBB on feb. 5th for a protune. Do you think hey will be able to solve this problem or should i try and adjust the wastegate? any suggestions?
