Where's a good place to get the 3" Pulley? Does it make that much difference? Should I go smaller? Anyone running with it, did you have to retune the car, chip it ? Anything else that should be changed with it i.e. injectors, intake etc... Let me know thanks!!!

 

I run a 3" with the rev it up kit. I think you need injectors with anything smaller.

Not running a 3 inch as of yet (i'm having it ordered soon) but you do not have to retune the car. Injectors aren't a must either but you could buy them if you want....personally I wouldn't and would wait for the GM Stage 1 kit to come out (ecu reflash and injectors). However, you will have to get a range coler spark plugs. I'm going with the NGK spark plugs that South Florida Pulley Headquarters sells.

 

hey im running a 3 inch from intense. with a AEM cai. no other tuning or anything. its awsome! im putting down almost 15.5 psi. although i did change my spark plugs to the ngk iridiums. AND NO CEL!!!!! the whine is insane
