I just recently received my FWI from intense and I also just received my autolite 605'*. I have not done my PCM yet because honestly I will need a little guidance on the settings. I also have my exhaust opened up pretty good.
My question is . . will I get a noticeable difference if I change my pulley to a 3.5. Or would it make more sense to do the necessary upgrades to put on a 3.4 pulley. I don't really want to do a 3.4 because of the possible KR issues. Especially if there is a noticeable difference with the 3.5.
I'm really just looking for some opinions. Thanks
