Im looking to learn how to do a segment swap on a 2004 chevy 2500HD 4x4 6.0 LQ4 .. iv been reading on how to do one, i need to email tech and ask for the segment swaper.. ok now then, do i need to look for a truck vcm or just any with the same OS and, is this what i need to be able to go from a 2bar to a 3 bar upgrade all that's allowable is 2 bar on my OS ?
Thanks Monty
