Need help with TC issue
I just installed a new intake and larger TB, on an 3200 stall A4 C5 so I was doing some tuning. did some full throttle runs and AFR looks good.
Problem: Did a couple of starts from a stop, and the car just "loaded" hard. It feels like the TC is locked up, and not flashing.
What could cause it to lock up, if that's the issue?
