Your torque is up there and your HP is about where it should be...maybe a little low but nothing to worry about. The 1/4 time is not that great but that depends on alot of factors too. What was your 60ft., elevation, when was your last tune up, things of that nature. Also that slipping tranny is killing you. And your sig says full exhaust. Is that longtubes and catback or what. I ask because different people have different definitions of full exhaust.

EDIT- just saw your 60ft. in sig so you about good but get that tranny fixed!

Thats pretty good for A4 with 2.73s. My car with CAI and mids ran like a 14.0 with A4 and 2.73s. I can't drive too well though...2.2ish 60 fts. Mine only dynoed like 240 to the wheels, but I now think the head gasket may have been goin at the time. Hope this helps.

I have 2.73's my 60 ft was 2.1, I spun a little out of the hole. I have pacesetter mid lengths, y pipe, high flow cat, flowmaster cat back, my elevation would say maybe 500 ft above sea level. my last tune up was right before i ran these numbers, i did myself new opti, plugs, wires, oil change, changed rear diff fluid, tranny was slipping at the time though, but now she is fixed so i need to head back up to sac and see what she runs.

Yeah I think you'd be runnin much better with a better 60. Your hp number looks really low but that could be because the A4. What dyno did your numbers?

I took mine to a 12.9@105 on a 1.8 up at sac, they usually have pretty good prep on test n tune nights. Dumped headers, cai, tune, tires.
