I took a look at a truck I'm interested in buying last night and of course the owner says it doesn't have a tune, never been beat on, etc. It had the the dtc light on so I pulled the codes and decided to pull the tune while I was in there. Looks like a bad #2 & #6 glow plug by the way and it most certainly does not have a factory tune. I haven't done much with diesel tunes So I'm hoping someone could take a look and tell me if it looks like a safe tune.
Truck has 144k miles, banks intake, flowmaster exhaust. Judging from the tune the egr and dpf have been removed but it was dark and raining out so I didn't crawl underneath to confirm. Also has a "Rolling Big Power" custom gauge cluster. I don't know if this is part of a package or what the story is.
