Finally the car is pretty much done... I am looking at pulley options right now so wanted some opinions. I have done all the reading but some further input would be nice.

I was thinking of an MPS system but a few local guys have a 3.4 & a 3.35 press on pulleys for next to nothing. I am hoping to get Overkill to do an in car tune as well. I am thinking I start at a 3.4 but don't want to start there if these mods will support in all likelyhood a 3.3 lets say. An MPS system will be over $100 in comparison but then what pulleys do I purchase?
From people's experience with an in car tune will I likely get lower than a 3.4?
