Alright guys I just bought an 03 lb7 crewcab last week and am wondering what you guys would suggest as the first mods to do to it, I was thinking along the lines of a cheap programmer and exhaust. Any suggestions on brands? I dont know a whole lot about the diesel world but so far i'm already enjoying it! Thanks and look forward to ur feedback. also if anyone knows anything for cheap to do to it i'm all ears... not lookin to make no crazy 1000 horsepower drivetrain just want it to move well and still get decent mpgs!
