Aftermarket TB & Pulleys

Looking into purchasing both of the bolt-on mods. Anyone have either one or both on their rig? If so, did you see a noticeable difference? Or did it just seem like a waste of $$$

I had a pulley on for about a day...it ran the AC so slow at idle it almost wrecked it. The throttle body I can't say anything unless you are talking about a spacer...they don't help.

I'm actually talking about an aftermarket replacement throttle body from bbk or comparable.

That sucks about the pulley though. I don't have AC on my setup so at least I wont have that problem.

I thought I would have trouble with my electrical system with the pulley but I didn't. If you don't have AC then I would say go for it...I could tell a difference with the pulley. The one I had was made by March.
