Car goes 8.8 in the 8th at 84 MPH. Spinning the tires, need some traction, but I need a guess on my HP and tq.

K&N air cleaner
ECU tune on Dyno (previous owner)
Air Box cut out (little DIY mod)
Pace Setter headers
SLP Y pipe
Cat delete
Borla exhaust
Aluminum driveshaft
A4 trans with shift kit

330 RWHP would be my guess.

stock LS1 motors make more power than that, you numbers are way off.

Thats what I thought also, he said my exhuast was too restrictive, it was also in in June on a Mustang dyno. He also said that after every thing I done I only added about 20rwhp. He said that all stock LS1s that come in the shop dyno at 260rwhp.
Gonna find a different dyno after I get my new exhaust on. Ill see if I can find the dyno sheet and post it up here.
Compensating for the weather he said it should have been around 290.
