Rebuilding Detroit

[Brock]

Change the fuel pressure regulator / check valve on the back of the head. It isn't exactly a cheap little part but I should 100% be done if you haven't, have them manually test fuel pressure after to see if the pump should be done as well.

The valve on the back of the head is not to be confused with the check valve everyone talks about online, they are almost always referring to the ddec iv engines which are only a check valve, on the ddec v it is also a pressure regulator.

Mommaburt can tune that thing absolutely beautifully for a very good price, I'm not sure how often he's on here anymore but Rawze or myself could get you a contact info if you message either if Interested.

I agree with Rawze, alot of the Detroit 60 tunes are butcher jobs, not saying yours is though.
