Looking for an economy tune for my 08 6.4

[hoondog]

Hey guys,
Looking for an economy tune for my o8 f250 crew cab 4x4. I have used all tunes. stock is getting me 10.5 mpg, 50 hp is getting 11.2 80 hp is getting 11.8 and extreme is getting 11.8-12.1 mpg. My mileage has been consistently dropping since truck was new and predator was installed. I do have 5" lift and 35x12.5x20 tires but mileage is with above installed. I am trying not to do a dpf kit as washington state is giving out tickets for trucks blowing black smoke as it gives them cause to pull us over if the truck blows smoke, screwed up but that's the way it is. Any help would be appreciated. Thanks guys, you have always supported us here, Keep it up!!!! Thanks, Trying to keep the mileage up!!!

Are you on the latest revision?

Generally, if there is a loss of mileage, it is an issue on the truck, fuel filter, clogged DPF, bad injector, etc...

Yes, I am running the latest revision (9r12a). I have 27K on the truck, Just serviced with a clean bill of health (asked the stealership about the injector health and they said all is good). New air and fuel filters, fresh oil, etc... I had been running the stock tune just to remember how it differed from the diablo sport tunes and that is when the mileage really took a downward turn. The tunes are bringing it up slowly again but can't seem to get over 12 MPG freeway driving. You guys had given me an economy tune a year or so ago but I lost it when my hard drive smoked on my laptop. The mechanics at Ford were saying that I should be happy at 11-12 mpg as most around our area are only getting around 8 mpg. Somehow that doesn't make me feel good considering I got 18 + new before the flash. I was also curious about the speedo fix, anything yet? I asked last year for a custom tune and there was some issue about not being able to write one for me. Any help would be appreciated. I am currently using the tow tune as it seems to get me the best all around driveablility.Thanks guys,

try using the Monster Fuel additive it helps to get rid of the smoke all the time. I have been using it for 1 year and it's great. takes out the knock and ping and getsrid of the smoke..
