I have a gm stage 2 kit, with 2.99 pulley. Also zzp midlength h/dp zzp h/e, catback and cai. My ? Is will getting a tune from them give me much of a power diff, and how much. Also any pro and cons thanks.

 

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

 

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

 

get 60s and 2.85 and stg1 tune.
you'll be fine

 

Thanks I believe I will order from ottp monday.

 

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

 

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
