I think offering advice that could help him would be better than putting down his time

i may have alot of mods but i only have 3 mods that "add" horsepower and that would be the cam, roller rockers and tune... and i have 3 mods that "free" up horsepower and that's the CAI, exhaust and EWP...

i may be short on some power but i'm sure the 87% humidity had something to do with it...

i'm looking into getting a dyno tune, dump the bosch o2's and set lifter preload to 1/4 past zero while running (instead of 1/2 past while cold)...
