what kind of mileage gains does a dp tuner give you on a 1999 powerstroke with a 2002 motor in it?

Do you have the 2002 PCM installed too or just the motor? Econo tune, maybe 3mpg gain. Any power tune and you're right foot gets heavy for some reason

Still the 1999 one, i guess they changed the injecters to fire more times for 2002 or something. but it is probabaly not doing that because of the older PCM.

I belive he has a tune that can activate it for a exhaust brake tune or something. They can also turn it off as well. In my hi idle i had Jody turn it off so it doesnt make that horrible noise when its warming up in the winter

He can put you in a decel tune that activates the EBPV to close off. I just got it and have not had the opportunity to mess with it much.

I'd like to know also. Th e best that i can get is 15 with the cruise set at 65. I have an automatic tranny and have thought about going to a 6 speed if it will get me to 19 mpg or so.
