MPG-6.4l
-What are ya'll averaging for MPG before and after chipped with the 6.4L?
-What kind of chips are ya'll runnin'?
-What is the best combo. for chip and intake concerning MPG?
-Does removing the DPF really increases the MPG?
-Does removal of the DPF affects the warranty, and do you have to reinstall for emissions testing?
-What kind of chips are ya'll runnin'?

Bone stock I got about 16 mpg per tank or fill up. Now with the mods I've done which is in my sig I get 20-22 mpg per tank or fill up. And the warranty just depends if the service manager will over look it or if you have a relationship like I do with a local dealership and they don't care.

The most popular chip/tuner seems to be the Spartan tuner.
It seems that most people report MPG gains after deleting the DPF, but most of the time that goes along with a tune as well.
And absolutely 100% removing the DPF affects warranty! If you read your owners manual that comes with the truck you will see Ford talks about emissions system modification and "tuners" and "chips".
As jac08f250 said though, you may get lucky and have a service manager that will look the other direction. However if something happens to your truck directly as a result of modification don't you think you should take responsibility for it? Instead of making Ford pay for it?

So if the Spartan kit with DPF delete is $1250 and you go from 12MPG to 16MPG with the kit (average) and you drive 12K miles per year and diesel is $3.10/gallon then it takes about 2 years and 25,000 miles to break even on the cost of the kit. This assumes a lot and doesn't factor in the possible warranty denials which could be *very* costly.
I dunno....sounds like it's a big risk vs reward at least to me.....

at 3.10/gall you need 403 GALLONS of improved mileage to cover the cost.. regardless how far u drive.
if Towing mileage is only 1 mpg improved.. then it will be slower payback.
SO.. it sounds like this is not a 'payback' scenario.. more a more power scenario, less restriction..(less repair?)

I'm not familiar enough with diesels to understand the "less repair" part of your statement. How does less restrictive lend itself to less repair?

now figure in ownership miles.
diesels can go 300k miles or more (without fuel in the base of course lol.)
i know one thing,the sooner that DPF crap is removed,the sooner you stop pouring in fuel into the base of the engine.
long term,the poor 6.4l doesn't stand a chance.you know what diesel does to main and rod bearings? it's not pretty.
you dont want fuel in your oil.....period.let alone watching the oil grow a whole quart! or more! ouch.such a shame.these engines are going to get a bad rep due to this over the years,you watch and see.
i know years down the road,if i go looking for one,i wont touch one without documentation of DPF delete @ low miles.
Four Lethal Diesel Engine Oil Contaminants
Fuel Dilution
Frequent starts of an engine, excessive idling and cold running conditions can lead to moderate fuel dilution problems. Severe dilution (excess of two percent) is associated with leakage, fuel injector problems and impaired combustion efficiency. These are symptomatic of serious conditions that cannot be corrected by an oil change. According to one reference, 0.36 percent of total fuel consumption ends up in the crankcase. Problems associated with fuel dilution include:
*
Diesel fuel dilution in cold operating conditions can cause waxing. During startup, this can result in low oil pressure and starvation conditions.
*
Diesel fuel carries unsaturated aromatic molecules into the motor oil which are pro-oxidants. This can result in a premature loss of base number (loss of corrosion protection) and oxidative thickening of the motor oil, causing deposits and mild starvation.
*
Fuel dilution can drop the viscosity of a motor oil from say, a 15W40 to a 5W20. This collapses critical oil film thicknesses, resulting in premature combustion zone wear (piston, rings and liner) and crankcase bearing wear.
*
Fuel dilution from defective injectors commonly causes wash-down of oil on cylinder liners which accelerates ring, piston and cylinder wear. It also causes high blow-by conditions and increased oil consumption (reverse blow-by).
*
Severe fuel dilution dilutes the concentration of oil additives and hence, diluting their effectiveness.
*
Fuel dilution by biodiesel may result in higher than normal problems compared to diesel refined by crude stock. These problems include oxidation stability, filter plugging issues, deposit formation and volatility resulting in crankcase accumulations.

Leave you stock air filter. My uncle has had two engine go over his aftermarket air filter on a 6.4 and he brags up how he gets 2 better mpg over it. I have a 2003 F450 with the 6.0 and I get 9.5-10 and I wouldn't care if I could get 14 with a air filter kit. Fuel is cheaper than a engine.
