Stock 6.4 tuners
Hi Guys, I would like to hear from those of you that have installed a tuner on a 100% stock 6.4 with the DPF intact.
I tow with my F450 and have no intention on removing my DPF, however this truck in a pig, no power and no fuel mileage.
When you have a newer Chevy Suburban gas pot passing you like you forgot to start it, up a 5% grade pulling a 31' travel trailer and me with my 11'-6" truck camper something has to change!
More power and a couple of miles per gallon would be nice, but from what I have read, the DPF would have to be removed.
I have had the truck to three dealerships and all three say there is nothing wrong with it.
Does anyone make a tuner for the 6.4 that will help a factory stock truck?
