Dyno with longtubes & CAI

I finally dyno'd my car after putting on the longtubes and CAI. I had some problems with the clutch originally that turned out to be a flywheel that was turned once too many. Solved that with a flywheel shim from the local machine shop and no more problems. Anywho, car dyno'd 260 rwhp and 290 rwtq bone stock. Went to 299.9 rwhp and 336 rwtq. It ran a bit lean (14.3:1) before 5000, so I might get a little low and midrange power if I richen it up. Complete mod list below.

K&N Cold-air intake
Jet Hot Hooker Longtubes
Ghetto true dual 3" exhaust w/xpipe
TB Coolant bypass
Taylor OVC wires on drivers side (don't ask - i don't know how to make plug wires)

Makes me feel good about my car with that much of a gain. 40 RWHP and 40 RWTQ. I raced an LS1 a week ago that runs 13.1 @ 107 and pulled him just a hair from 4000 rpms in 2nd to top of 4th. Granted he's an auto, but I weigh 400lbs and my 270lb friend was in the car with me. The guy in the ls1 weighs maybe 180 (going super high) and he had a 150 or so lb passenger with him. If my car traps 107 or better I'm gonna flip. Probably gonna hit up Darlington this week, slick it up, maybe even spray it. Oh well, done rambling. Been the best birthday I've had in a long time!

If you dont hit your goal, mabee you should drop a cam in there to WAKE it up even more.

Have you gotten it tuned yet? I remember you saying something a while back that 305 is what you got right after the install. 320rwhp is what seems to be the norm for A4s/bolt-ons/HC kit while upwards of 330 for the M6s; both after tuning.

And don't forget, the M6's will dyno about 10-15rwhp higher than the A4s.

[EDIT]- Nevermind, just saw your sig And good numbers too brain
