One of the big misconceptions on the platform is you need "X" or you need "Y" mods...my car took rockers to get rid of knock on a 3.5"...then again...I only had PEM's and a 3" DP.

If you can get away with it knock free (granted I wouldn't try it without a way to scan, an MPS system so you can swap back to a larger pulley if you CANT get away with it, and a way to tune the car...preferrably with a wideband/DHP or HPT system)...more power to ya
People have a bad habit of taking guidelines as fact. If you're modding past a 3.4" pulley your first (or one of your first) purchases should be a scan gauge.
