I've added 1.6-1 roller tip rockers to my otherwise stock 120k mile L83. Auto, 3.07's, and cold air mod w/K&N. At Houston Raceway Park at 68F and almost sea level:
14.7@92mph followed by the same 2 more times. Previous best was 15.2@89-the rockers really make a difference!

All runs were made shifting the A4 manually. It was fun pulling a car length out of the hole on most of my runs.
We made a bunch of other runs tuning the A4's governor that were not worth mentioning here.

Congrats to you and JrRifleCoach!
JD, is this your whole NA mod list?
For your nitrous runs, is that a wet kit or dry?

I'm not sure if I still have any slips to read, but I remember the basic numbers.
1987 4+3 Transmission
Lid, Foil, 1000cfm TB, Ported Plenum, Big Mouth IM, AFR 195 heads, TPIS cam, TPIS Long Tubes, High Flow Cat, Borla Y Pipe, Dynomax Mufflers, Hypertech Ignition, Retuned ECU, Dual-Friction Clutch, and super cheap street tires.
I ran 13.3x @ 106.xx mph /w a 2.0x 60' in Sac, California
I took off just like a stop light on the street so it wouldn't get hurt .

New Best
I went to the Sacramento Raceway today 2/17/07 and made three runs. Last year the fastest run was 14.1. I changed two things before going to the track today. I installed March under drive pulleys and I pulled the cat (for today only) and installed a straight thru BIG PIPE I built myself. All other things are the same as last year, except I now have 214,000 miles on the car.
1st run
60 ft 2.092
1/8 8.747 @ 80.545
1/4 13.613 @ 99.478
2nd run broke out the rear end bad and shut it down
3rd run - dropped street tire pressure to 26
60 ft 2.122
1/8 8.808@ 80.649
1/4 13.663 @ 102.395
