This my first A4 car. Ive had two other M6 cars.
Its a H/C
Art Carr 4L60E w/stall
Moser 12bolt

Anyhow, Just bought the car like it is, needed
a tune, searching for an idle, converter not locking up,etc. but most of all.
When the car upshifts, no matter how much gas you give it,racing or leaving a redlight beside a cop, the motor cuts out right after it upshifts!
So I sent the computer off to a well known tuner. Did an awesome job!
driveabilty was dead on. But it still cuts out after it upshifts. After it hits a slight dead spot, it goes into its powerband. Its like it just does'nt pull straight through the shifts.Its not a big cam. it is a bigger converter.
But anyone had this problem before? I can tell Im losing alot of MPH because of it.
It sounds like torque management, but surely that was deleted.

 

It would seem that your tuner missed a few calibrations. If you have a scanner, you may see that shift torque is still pulling power down.

 

Thanks, I figured it was something like that. But I don't know much about tuning.
