So my buddy has a 2010 wrx with 3" cobb downpipe, 3" invidia catback, process west TMIC, Cobb sf intake, Grimmspeed ewg up pipe, tial 38mm waste gate, and grimmspeed boost solenoid.
scenario: Just recently installed the upipe and when it was finished the waste gate wouldnt open because the shop didnt have the resources to tune and the boost would spike dangerously high. Later that week the shop did a road tune, because the shop doesnt have a dyno, the car gets to 17 lbs of boost and throws a cel (P0108) and starts to drop boost. Apparently the guy who did the road tune used a cobb accessport stage 2 map and then used the accesstuner to tune it.
Has anyone had this problem or know what it is? I suggested taking it somewhere to get a protune on a dyno, is this a good course of action?
