my recommendation would be to take it to a stealers$it (or remove the ecm and take it to one) and have the ecm programmed back to 100% correct factory program for the engine and truck for a few hundred $$ until you get your other problems fixed. It will run even dele^ted if u simply unplug the egr temp sensor over on the intake side of the egr piping. it will have a check engine light on in the dash, and a 10% turbo derate, but at least the destructive programming will be gone, and it should run well like that till you get your other problems solved.

This will eliminate the bad programming and let you focus on the rest of the issues.

After you get it running right again would be the time to seek a new program if ya wanted to do so. Some ppl on here learn to do this themselves (it is not nearly has difficult as one would think), and some have someone make it for them.

- Go get it flashed back to factory.

- Invest in an inline-6 adapter off ebay + a used windowz 7 or 10 laptop.

- Straighten out all the issues with the truck, fuel system, etc... get it runing right again.

- Maybe drive it a few weeks on the factory program to make sure its all good again.

- After that, if ya want a custom program back in it, there are ppl on here that can be trusted to make good program with you for it that will not rip u off. That or u can make something yourself if ur a savvy person with a PC who can do things like run a spreadsheet etc. It is not as difficult as ppl make it out to be.
