So here is a 2010 SS with L99 we just finished this morning.
The mod list includes:
Vortech Si Trim Supercharger Kit
Vortech Fuel Booster
3.33" SC Pulley
ARH 1 7/8" Headers w/ cats & x-pipe
Flowmaster Exhaust
Custom ECM Tune
So this car did
317 RWHP SAE stock and we got it to
568 RWHP SAE after all mods & 9.5 lbs of boost.
The 1st graph is before and after and the 2nd is with AFR and boost. Sorry we didn't start the runs in the same place on the before runs.
