Performance up Grades
 

I just got a 04 2500 and I am looking to do some performance upgrades! It already has had the muffler and cat taken off! I am mainly looking for better fuel milage. Any recommendations on Chips would be great!

just about any programmer can give you a few mpg better, if you are strictly going for mileage gains, having someone custom tune the truck with EFI live will be your best bet.

Im on the EFI bandwagon:choochoo:

EFI Live is the way to go with a Dmax... Your gonna need some tranny work to hold the added power tho!

Had a dmax with a bully dog chip on it come in for a set of gauges and just done a set for my buddy(05 w/zf6) and there's no comparison. The efi just feels better all the way around, but they both claim 20+ on the highway. I've drove the 6 speed truck off and on a few times and it really does get awesome fuel economy as long as the skinny pedal isn't stuck to the floor. Intake would be a good idea too

yeah a higher flowing intake wouldn't hurt but if he is only mildly tuning for MPG then it probably won't do anything. a custom EFI Live tune is your best bet for mileage. personally i would not go any higher then about 40 HP over factory on a stock transmission, and this can be done on a mileage tune.

Very true, just thought i would throw that out there though. Be a simple upgrade and it would help him down the raod if he chooses to add more power later.

even more true, good point
