If i wanted to push out more psi on my stock ss-sc?

 

Pulley.

 

Also bigger injectors depending on what boost levels (size of pully you buy), then a better flowing exhaust setup...

 

so like a gm stage 2?

 

gm stg 2 has, somewhere around a 3.0" pulley, bigger injectors,( probably 42) and smaller belt, youll be boosting like 15 lbs. Now if you want to boost way more and make way more power, get intense stg 5. Youll boost like 20lbs and make like 270 and 270. crazy stuff if you ask me. I cant wait to get mines.
