Evilution

car is a 01 formula it was stock internal with 4.56 gears a detriot locker, full exhaust, ls6 intake, 85mm TB/MAF, lid, free mods, and so on. basic bolt-on car made 338 rwhp throuh the 4.56's. i am going cam only. after searching around a lot and working with my mechanic I came to decide on a 235/247 .575 .555 109 comp thumper (291t). running dual patriot gold extremes, ls7 lifters, 4200 stall. my questions are:

1. should i go speed density when i have it retuned or stick with a MAF
2. how much could I expect to gain from a fast 92 or 102?

any input is appreciated. and yes this is a weekend warrior/ track car not a daily driver.

Thanks,
Marty

Id recommend to go SD and ditch the MAF. with rpms that cam will want i think it might be worth the gains to go with the FAST setup
