I was just wondering if i could run a 3.5 inch pulley on my car
the only mods i have are a K&N CAI and a ubend delete. (stock PCM) I know that all cars are different but i just wanted to see if people who are running the same mods are having any knock problems. Really what its coming down to is im looking for some more HP but im not so sure about changing out my pcm. another quick question- is there anyway you can tune a stock pcm? what does a hypertec tune do?
thanks for all your help
