My car I have listed under my name (currently blown motor from water) had 322hp and 321 tq to the wheels before the lt headers were added. That was also down in FL in hot weather. So you should be around there.

Also i ran a 12.8 at 105....prob mostly due to the suspension though but thats where you prob will be

I've got everything you have besides long tube headers and I put down 301 RWHP and 300 RWTQ after the tune. On average I've seen guys w/ the headers putting down 305-310 RWHP and around the same torque #'s as well.

I turned a 12.9 @ 107 w/ just exhaust and tires. Now w/ all the new mods and good driving I should have no problem seeing 12.50's or better...
