I got a dyno tune last week.
Same headers (SP 1 7/8" LT) and same CAI inc intake.
I put down 374 rwhp and 396 rwtq on a pretty hot and humid day in louisiana.
Here is my video and dyno sheets http://www.camaro5.com/forums/showthread.php?t=308455
. With a good tune, your car should be nearly identical.
Lethal racing can email tunes also, if you want my same tune. Trans shifts great now.
