Hi all I need a little help with diagnostics. Background, BWR s/c installed 2 weeks ago with charliex tune. Ran awsome. Took a trip to naples and back 2 days 300 miles. I initially broke it in with 100 miles. Got gas after returning hme and check engine light goes on steady. no change in performance. Hooked it up and it was a Po171 code. Cleared the code and cleaned MAF sensor with MAF cleaner. The wires were a little dirty. Now there is a stumbling at mid throttle and the power is way off as if there is no boost. Idles fine and throws no codes. I do hear a wooshing at lift throttle when shifting even though it is warmed up. This used to only happen when cold. Any ideas would be appreciated. I will check for vacuume leak this evening post throttle body as well as line to bypass valve on s/c. Thank you in advance! Tommy
