Hey guys I need your opinion I live in Utah and have GM stg 2 inj and looking to go 60s our elevation is high but need some help with the pro's and cons

car_guy_09

pro's are more fuel and more room to grow.

Cons are you need a need tune and injector harness.

In the end there really is no down side

Considering your future mods I would grab them. You are already pushing the limits with your modifications and upgrading them will be safer for your system. A lot of people dont realize that a 2.9 on a gm stage 2 tune in high altitudes can put your idc's well into the 90s - 110s. However it depends on all sorts of factors etc.

Either way, upgrade the injectors, get a tune and you will be much happier.

i do see the point here, and i am a tuner so i know what can go on. I live in a elevtion above 4k, and ive tuned a cobalt with a 2.8 pulley and the idcs never got higher then 88% reason why was P.E EQ and ect. u can tune for the pulley but id much rather tuned the 2.8 for 60s more room, and safer

You guys think my my MPG will decrescendos a lot or not enough to notice and anybody got any 60s and a harness for sale

Sorry to bug again but with my mods and going with trifecta stage 3 what do you think gains would be with 60 s

Erick161

I dont think you'll see gains really, just that it will be a necessity here shortly if you decide to pulley down and just be safer in general, that way you arent maxing out your injectors.

I'm thinking of moving to a 2.8. I think ill get the injectors from zzp

up here people can run 2.8's with idc right around 85 to 90 on a tune...from what i have heard unless you go lower like a 2.7 the 60's are a little harder to tune up here.... that is coming from matt up here

If I stay with 2.9 and have Vince and Matt tune me think it would go well

I am running a 2.99" pulley with GM Stage 3 tune and I dont see the need for cooling mod unless you are doing constant back to back pulls
