Not much going on in the SD section, huh?....Well....I got a Predator tuner for my 2000 7.3 PSD and put the 80hp tune in. It ran great except that I got an oil leak from somewhere. I cleaned the engine and removed the tune....no more oil leak. I've seen industrial diesels "slobber" due to insufficient load....is it possible that the tune is dumping more fuel that the engine can burn? Any suggestions are welcome.
