So ive been looking around and keep finding so many different answers. What else will i need to do to run a 2.8 inch pulley. I currently have a full exhaust, cai, stage 2 clutch, and gm stage 2. Will i need bigger injectors or can i run the 42lb, i dont race all the time.

 

you can run the 42s, but you'll be putting out a lot less power in order to keep them safe and happy. i ran the 2.8 on only....well, nothing. i just had the pulley and 60s for about 2 months with no issues. but he also tuned me with that in mind. and then after i got my last mod i got retuned. go ahead and get a h/e and option b style tank, or get 60s.

 

will the stage 2 tune be ok with 60lb injectors

 

nope, you need tuned for those

 

no .... the GM Tune is designed for the 42lb injectors.

 

no it will not be okay. if you want to pulley down but keep everything else the same put a 2.9 on there. if you want the 2.8 you're going to need a tune regaurdless if you switch to the 60s or keep the 42s
