Hello guys I'm still trying to get my car running right. I've narrowed the culprit down to the MAF sensor or something related. When I unplug the MAF, car runs fine, pulls hard, hits target boost and fuel trims are decent. MAF plugged in, hesitation at low rpms, can’t build boost(bleeds off via wastegate), and I get a epc/cel and then limp mode if I use more than 50% throttle.
Faults scanned via accessport are:
P0606
P0068
P050A
Also scanned using Vcds, codes seemed more accurate
P1335
P0068
P050A
P2261
Two of which are MAF related. I've already tried replacing the sensor with a new one, no change at all. The car is being tuned by stratified. The only thing I can think of at this point is that the tuner calibrated for Cobb’s MAF sensor and not the stock one. Anyone experience anything similar, or have any suggestions on how to fix. I emailed my tuner about the MAF but I'm guessing I won't hear back till after Christmas.
Almost has to be a tune issue at this point right? I've already tried, adjusting my wga, changed my diverter valve and replaced sensors, no change at all.
Thanks for any help.
