What gears are you running with the A4? The switch to an A4 will cause you to lose approximately 5% power to the rear wheels. That being said, you need to get to a dyno and see what's happening because something doesn't sound right. You should be blowing the doors off of stock Z06's, if you have the C2 cam.

 

Something is obviously wrong. If you went to an auto with a converter, I would think you'd be doing better at the track. As stated before, you will lose a little more power on the dyno, but the engine power should be the same. Id have it checked out. If youre located in Houston, theres several shops you could go to. I had all my tuning and dynoing done at MTI.
