i noticed very little gain. helpd the power curve a little and got more 2mpgs more.
my mods were stg2 and full bolt ons

Durtyss

Well how about ottp stage 1 power, power diff. I'm just afraid that might be to much for my stock clutch with them.

Bump

your clutch is going to start slipping with those mods. mine started slipping with stage 2, full exhaust, cat delete, Cold air, and a polished tb. I couldnt imagine how bad it would have been after i pullied down and got a new tune. btw i went to a 2.7 and 60's. its deffinetly worth it. Just watch your self youll get in trouble

Make sure you do the cooling mods though, or youll get no where.

Ya I have a h/e so I should be fine.

ur clutch was prolly goin bad anyways thats y.
mine holds fine had it for 16k miles no probs and i got 60s, 2.9, intake, full exhaust, tune, h/e, plugs, and stu mod

Who's tune is better zzp s3 or ottp stage 1. Also what's best pully 2.8 2.85 or 2.9 don't wanna push blower to hrd. I was thinking 2.85 also how much harder will it pull over gm s2

drew1991sf

i would say a good amount over stg2. and go with ottp stg1. and do a 2.85 if ur only cooling mod is a h/e safer
