Hi all, Bought a 06 LBZ Duramax about 2 months ago. Came with EFI live and dsp5 switch. Seemed like it had no power at all and was black smoking bad, checked for boost leak only to find the cold side pipe wasn't even in the rubber coupler and had to get a new turbo clamp. Once I fixed that problem it had a lot more power and didn't black smoke as much. It is still not running up to par though, some pulls still lug black smoke and still feels like its at a loss of power. I want to get it retuned but idk how with the efi live, whether its self tuning or just buying a whole new efi live setup. I think I have the autocal that plugs into the truck and I could read codes and clear them but when I click on download tunes or anything it doesn't do a thing. (It has a good amount of codes throwing at me like U0100,P0101,P0405,P0700,U0106, and P0118) Also when I click on the data option or other button it gives me the names of previous owners who payed efi live for tunes. I would think if they already paid shouldn't the truck be running pretty good, but again I know nothing about tis efi live. Owner that I bought it from knew little of what was done to it, but from my discoveries and there knowledge, it has a egr delete, shifter kit in transmission, and S&B Intake(I put new filter on). + it is straight piped. I also thinks it needs at least 1 injector because it white/blue smokes and then stops after warm. Could attach pics of engine bay, as there is wires that were supposed to lead to a speaker system but previous owner looks like stopped midway.
