I'm in the process of tuning my vehicle.
I'm reading values for AF Correction dipping into the high -28 to +26. AF Learning maxes out at -8 and +10.
AFR is steady at 14.75, 22 off throttle.
Tuner diagnosed it as vacuum, boost leak, water in MAF extension, or intake filter positioning. Rechecked all of this, replaced all the parts except MAF sensor.
Cobb Big SF
Catless Turboback Exhaust
Boomba BPV
GS TMIC
GS Charge Pipe
DW300 FP
IAG AOS
Accessport
Turbo Inlet Pipe
Killer B Headers
Car runs absolutely fine, but I can't get over the fact that my AF Correction is so off. I did 3 smoke tests and found no leaks. Could it be a vacuum line on the BPV/Inlet? I'm going to be taking it apart tonight.
Just need a few more ideas on what to check before I start swapping in my stock parts.
Thanks!
