first time dyno #'s Just wanted to see what you guys think, mods in sig. The y-pipe is 2 1/2 inch with high flow cats
it put down 327rwhp and 350rwtq
the car hasn't been tuned and the air/fuel ratio was slightly above 13 the whole time, maybe 13.5 at the highest point from 2-3 grand then went to 13, and then dipped slightly below after 5600
Wanted to know if tuning would get much more out of her?
I'm happy with the torque but was hoping for a little more hp
Any suggestions or comments would be appreciated

Not to bad of numbers...Its not one of the factory beasts that are floating around on this site but for sure a powerful car. A tune would help quite a bit to see those HP jump a little bit. I would guess maybe another 10 or 15 HP gain with one. Headers are a great upgrade but really come alive with a good tune.

Mostly stock cars have higher torque than HP #'s from what I have seen. It is when you start modding that the HP climbs and the Tq #'s don't climb quite so fast...cams, heads, headers, etc.
Good #'s though, and I agree with ls1wannabe that your AFR is right where it should be and tuning will not pick you up too much power if any. 13:1 is about right for a NA application.

as far as track times i would say get some nittos, come out easy all on the clutch, dont drop it just ease it out you should be rujnnin faster with you trap and your power....also if your only looking for 370 rwhp almost any cam would work....you could probly get that with a ls6 cam...but i would go with the tr224 good all the way around...thatts the cam im looking into

I think those numbers are really good. My brother has a 02 Z28 A4 2.73 and with a lid, Borla, and Predator, put down 327/350 HP/TQ. My 02 Z28 A4 3.23 with a lid, QTPs, cat'd y, QTEC, and Borla put down 354/360 with the 'verter locked, and 317/307 unlocked. I think your numbers are pretty good.
wuth a tr224/224 from what ive read you wont loos any down low...you will gain all the way along the curve...search for tr224 and you will get a bunch of dyno slips and you'll see they make pwer across the curve...its relly concidered a small cam for modern day standards, but make great power
