i recently got an 06 duramax, it already has 4" exhaust. i dont know much about diesels so can anyone let me know of any good mods for power and smoke and get the bang for my buck.
06 lly is same as lbz motor, no mouth piece needed. An 06 either way is same parts just different tune.did you own a cummins? more smoke does not = more power? so let your buddies with cummins sit and smoke while you leave them in the dust with quality mods! i recoomend the following order. but it would help if you put your trucks stat's 2 or 4 wd, lly, lbz? in your sig we can narrow the options down!
#2 sythetic fluids
#3 programer( if you dont plan on major mods a canned tuner but i regret not getting efi live from the begining it can grow with your truck)
#4 if your truck is an lly get an intake horn.
#5 forget it leave it stock you will never have enough money once you start!
