I have and 09 6.4 F350 -with a SCT, deleted all the DPF, cat, exhaust, intake, and on the Extreme program was getting about 20.5mpg - on the Performance setting I am getting 16.5, and on the Tow setting pulling a 27' camper about 14.2MPG

I'd go SCT with Innovative Diesel tuning, but there isn't such a thing as a tuner that wont void your warranty, no matter what any of them say. Your warranty work is up to your dealer, some are mod friendly, others are not. You simply will not get good mileage out of a 6.4 with the DPF still on there, you need to take that off and get the tunes to go with it for the best mileage. :c:

Just bought my new 2008 F450 Crew Cab 4x4 dually Fully loaded and I need a little advise on upping the HP and mileage.

I already have a 1975 F-250 4x4 400 hp balanced 390 4x4 18" lift 40" mudders, 2004 4x4 F-250 Crew Cab 8" lift 40" mudders, 2002 F350 Crew Cab 4x4 dually Fully loaded, chipped, 1999 F350 4x4 chipped and over 300,00 miles on the original engine and trans., and several lesser F250's and a Ford Tractor. As as my photo shows I've owned at least 6 other Ford trucks of various years and models.

Let's just say I'm into Ford Trucks.

What are the major bugs with the spartan. My cousin has a 6.4 and was keening towards this tuner. I haven't looked into it to far but I always heard good things.

can you do a DPF delete without a tuner that is capable of it? leanred the wrong way that bully dog is not the way to go!!!!

No you can not. You need something that will shut off the regen cycles.

You got my number :c:

With my IDP Livewire I did not gain much mileage but that is probably because I cannot lay off the pedal.

We've got some tunes to help out the guy w/his emissions components in place, so if you want to go the route of better mileage and not having to remove the DPF, we can help you with that.

I know, most are going to say you can never get good mileage w/the regen, but you can. On our shop truck, we are down to regeneration every 650-700 miles . . . during regeneration you will see 5-8 mpg and it typically lasts 10-20 miles . . . over the course of 650-700 miles, this is really a small blip on the radar and is easily lost in the error of calculating mileage. Our shop F450 w/4:30 gears has seen 16mpg on highway with all emissions components in tact with a tune that makes 400HP at the tires.

We do have higher HP tunes, but the additional air flow at the higher HP levels forces a regen much sooner. Regen on these trucks is triggered by a high pressure drop across the dpf, or 700 miles . . .whichever comes sooner.

Its not for everyone, but for those who don't want to mess with the legalities involved, its a good option.

how much for the spartan tuner?
