Have a 2006 F350 Super Duty 6 Litre Diesel 4X4 dually...........looking for a chip or programmer to improve milage and assit when I have my camper on - suggestions?

 

To really get the max gains, the first thing you need to do is get a bigger exhaust, then a cold air intake and FINALLY a programmer. Do it the upgrades in that order if you can't afford to do them all at once.

 

personaly ill go with a chip. ive used used a programer before, but i didnt like waiting 5min to put a tune. so i got a chip from DP and love it because i can switch from fual mileage to high performance with a turn of a switch while driving down the road.
