Thanks. I want to send the FICM off the 04 in and have them do that then swap it out for the on that is on the 05 when I get it back. That way my truck isn't down, and I will the stock FICM as a spare.
So with the PHP tune do I still need a tuner, I am running Innovative tunes on me SCT right now. The main reason I want to do the 58V is because I am moving up to the mountains and figure it will help it start this winter. Also how much was it if you don't mind?
