There was a thread just a few months ago. The thread starter had a 1st Gen that he had done just a few mods to and had increased his fuel mileage. Does anybody remember it? I searched for it, but can't find it.

 

I recall reading the thread, but that is about it.I'd like to know how some of these guy's are getting the milleage that they are out of a 4x4 as well. I get between 14 and 15.5 with mine.

 

Pete - Advance the timing and free up the intake and exhaust for better MPG. Let me know if you need help.

 

Thanks Dave. I've got a 4" exhaust on it now. I guess the intake side is next. I won't even see the truck until Christmas. I'm working out west in Utah, Montana, and Nevada until then.
