First, my car is on a stage 3, 91 oct, Cobb ots tune. Current mods are, Whoosh fmic, injen intake, and a j2 catback exhaust. I roughly hit 23lbs consistently before now. About two weeks ago I had been taking a friend on a drive and during a pull my boost limited to 18 lbs. I did not have a check engine light but I checked for one anyway on my accessport and found code P0035, Turbo Charger Bypass Valve Control Circuit High. Immediately after I reset my ecu and experienced the same thing where I am only hitting 18 lbs it seems like my ecu is converted back to stock and only hitting stock boost. So the same night I reflashed my tune, still hit 18 lbs, completely uninstalled my accessport and retuned, still hit 18 lbs, and finally disconnected my battery for 10 minutes and tried again, car still is hitting stock boost. I can't imagine there is any leaks because stock boost is 18lbs, I have gone through countless threads and there is hardly anything related to my issue. Any info helps, thanks!
