I will make this as short as possible.
Installed a T1 cam w/pushrods, springs and tuning.
Went to the track last night to test it.

1st Run - Car boggs off the line and doesnt accelarate
until 3/4 ways down. I was on and off the pedal - nothing.

2nd Run - ease into pedal - boggs again. 1/2 way down the
track it kicks in.

3rd Run - no tiny burnout - boggs slightly pulls good
hit 3rd gear - sorta a slug.
And it trapped the same as before the Cam?
I tested it on the road afterwards and it ran ok.

Any suggestions on what might be the problem?
Maf, Tuning, Computer, Internal, Coil, Plugs?
Any help will be good.

The car is a 1998 Z28 A4 with 65k. Computer Tuning.
Long Tubes, Cam, OffRoad Y-Pipe, Lid, 160 Thermo
Stock Rearend, Stock Tq Converter, Street Tires.

Sounds like abuse mode is kicking in. When you did your computer tuning did you add positive timing in the spark retard limit table? I use a value of 20 throughout the entire table. That way, when the pcm detected false abuse, I was still running 20 degrees of timing instead of 0.

I had the same issues with my 2001 WS6 A4. The car would bog and not rev over 4000rpms. In my case, it was the TransGo shift kit triggering the abuse mode.

I will have to check on the positive
timing, I did not tune it myself.
I checked the timing the night before and it
was between -24-27. It is picking up some KR somewheres.
