I KNOW THAT IT HAS BEEN DISCUSSED BEFORE

A friend of mine just bought an 08 F250 Powerstroke 4WD. He wants to tune it without doing the delete right know. What do you guys recommend? He is mainly interested in increasing fuel economy.

Mileage increase will be very minimal without a DPF delete. Maybe 1-2 optimistically. Buying a 500-1000 dollar programer is not cost effective for such minimal gains. I would say run it stock until he wants a DPF delete, thats the only way to gain significant mileage.

i am on the same boat your buddy is on. i know i will delete down the road. so im only looking at programmers that are capable of both. i have a Cortex from Super chips now and i have no complaints about it. but i am going to upgrade to spartan. H&S should have theres set up to do both by the time i am home. so im still not 100% on my choice yet.

When I first bought my truck, it had a Bullydog PMT tuner and stock exhaust. Bullydog will only do a 150HP tune (if I recall correctly) and I was getting around 9-10 mpg around town. And when I ran it in the higher tunes (which if driven politely should yeild better mpg) it would go into regen about every 75 to 100 miles.

I installed a Spartan tuner with the CAT/DPF delete and I'm getting 15.5 to 16 mpg driving the same route to work. I run the 250 tune, and just drive it normally. Seems that when I baby it, I actually get worse mileage.

I'll say it again, why the government and auto makers would improve on emissions by wasting fossil fuels is beyond me...

We are in the process of writing the software to do DPF capable tuning. The Black Maxx and Mini Maxx will be the first with this capability. They will, of course, be shift on the fly with 4 power levels. Likely they will range from 0-60-120-180 hp. With trans tuning. I think this will be great for the guys still under warranty but wanting to simply pick up some mileage gains without removing the DPF. Then down the road when they decide to use their truck for "off road" use only, they can yank that mess of an exhaust off and simply push a button on the tuner for DPF removed tunes.
