Hey guys,
I just bought an 07 LBZ GMC Crew cab, short bed, slt, with a 6 inch lift, s and b intake, 5 inch black turbo back exhaust w/muffler, fass fuel 165 gph, egr blocker plate, ppe outlet on cp3, race valve on fuel rail. What else should I do "motorwise" before I EFI LIVE it?? I want to get into the tuning portion of this because I sell all sorts of Diesel trucks for a living and I would like people to come to our shop to see "me" any suggestions?
