Re: Smaller Pulley And CAI Without A Tune?

Stock cars knock even with the stock 3.8 pulley so why would you risk chipping a piston by throwing on a smaller pulley..
 
Re: Smaller Pulley And CAI Without A Tune?

i ran my rockered header 3.4 setup on a stock tune for a while
 
Re: Smaller Pulley And CAI Without A Tune?

Stock the tune runs rich enough to run a 3.4 setup and probably even more. On the 3.4 setup I had on stock tune i was at 10.8ish afr.
 


Re: Smaller Pulley And CAI Without A Tune?

I'll be a guinea pig for it. Stock my car had essentially 0KR except at WOT shifts. Now with headers, colder plugs and soon a CAI, I will put a 3.6 on (after scanning). Don't plan on getting a tune either.
 
Re: Smaller Pulley And CAI Without A Tune?

I have headers, cam, stock tune, 3.4" and I still see knock. I feel there's crap causing my knock though, like vacuum leak or something. Just can't seem to track down my problem >.<
