So here I want to address the 07 duramax lbz. I’m curios on if there was ever a solution to staying out of limp mode without using diodes. I’d prefer to not add diodes, but if anyone has an updated more informative diagram I’d be grateful

New Here, Thanks to all of you who contribute to this site. It helped me fire up the truck I bought. Now I have a new problem and after running a quick search, I couldn't find anything relevant to my situation. The truck was running fine until I noticed it getting sluggish. The RPMs started...

I am new to the diesel side of things and I got an 03 duramax about 6 months ago. It started to blow white smoke after working hard towing my dune buggy around. I brought it in to the dealer and they said that cyl. 7 injector has a high balance rate and needed to be replaced. I decided to just...
