I recently fitted the COBB stage 2+ components( new downpipe and exhaust system) and I’m having trouble with it over-boosting. I have the car on the 91 octane ACN EBCS 2+ tune but it’s still exceeding 20psi in the turbo. The tune is supposed to target 16psi. Also when I got up to that 20psi the ecu cut the file and my check engine light came on. The car is a 2005 wrx wagon. Is completely stock besides the Cobb components that I installed. What do y’all think I should do?
