Here is a comparison of the before and after dyno results.

The car with 81 miles made 390hp and 378tq rock stock the first day i had it.

Now with the addition of a Roto-Fab CAI, 160 t-stat, and a tune the car picked up 26HP and 27tq. The tune eliminated most the ETC torque managment and fixed the 11.2 AFR (stock) to 12.7 AFR and timing from 18 to 23 degrees total @ WOT. The timing doesnt play that big of a factor on an NA engine like this and besides the LS3/L92 heads have uber efficent combo chambers and dont need alot of lead on advance. 416 and 405 are the final numbers.

I will probably get publicly stoned for posting this on the modern camaro site, because guys can barely get these #s with headers rofl!! Even w/o the weather correction factor it makes 394 and 385.
