I have a 2006 Gt with the m90 supercharger. I have only done the intake and stage 2 jed chip. I purchased a 3.0 pulley but haven't put it in yet because I don't know what needs to be done before:/ Also I have plastidipped my wheels! If you have any input please tell me. I will add pictures later when I figure out how!

ditch the chip n decide what you want to do engine wise, need at least headers n tune to drop a pulley. Rockers or cam or inter cooling to drop more n so on.

Hi..ditch the chip and put a 3.0 pulley on and over kill tune bam that's what's up!!

You'll need headers and a cam to run a 3.0 plus either an intercooler or e85 fuel. You've found the right forum to learn how to mod a 3800. The link above is a great start.
