WTF: Boost was fluctuating from 7 psi to 15 psi on APR Stage 2+
WTF?!?!?! I was driving today on the highway and my boost stayed at 7 psi. I went to Adrenalin Motorsports, took out the ecu to get it reflashed to 93 but never had the chance. When I was going home w/ the ECU replugged (still running 91), I was hitting 15 psi again for a lil' bit, then suddenly it dropped to 7 again! I checked for codes yesterday becuase I had a CEL and was also running only bout 7 psi and two of the codes was the following: 17538 - Fuel Trim: Bank 2 (Multi): System too Lean, and 17536 - Fuel Trin: Bank 1 (Multi): System too Lean. The codes were cleared last night and the CEL was gone, but when I checked for codes today, only two codes appear and the were the same as above. Anyone have any ideas? I tried cleaning the maf today also. Thanks!! Sorry for the rant...

You're limp and you may want to check for boost leaks.
Just take it to whoever did your turbos and make sure they double check all the piping. All it takes is one loose clamp out of the 70+ to make you go limp.

Hey Henry, sounds like your MAF is going bad. (m)
Why didn't Adrenalin reflash the ecu for you? I had this same problem before and it turned out to be the Mass Airflow Sensor. by the way this is BostonCactus (Barrett) give Julian a call and maybe I can take a look at it or let you borrow my MAF to check to see if it's the problem. I also have my old MAF that might only need to be cleaned with alcohol and that might work. other than that it sounds like maybe a leak or your TBB is popping off like mine was. See you soon.
