Well my problems described in recent threads about my boost dropping off quickly still exists and I've replaced a number of things outside of the MAF. The MAFs seems to be functioning fine, but I haven't ruled them out. The N75 replacement and all vacuum lines didn't make a single difference.
The next steps is to make sure the transmission isn't starting to slip and then tuning back to the engine accordingly. My car has 34,000 miles and an OCT ECU/TCU upgrade with BPs values, downpipes, cats and exhaust.
I am not get any codes in the ECU/TCU after scanning all devices with my VAG-COM.
Is there a measuring block that I can log to review to determine if my transmission is slipping? I want to make sure I am not chasing a transmission issue when looking at the engine.
Thanks,
Chris
