Story:
This past January my truck was in the shop for 25 of the 31 days of the month. On the way out to Glamis for New Years Eve the truck engine died and would not restart. The dealer had the truck for 2 weeks and I was told the #1 fuel injector was leaking. They replaced it and got my truck back on Saturday and Sunday coming home from a race in Lucerne valley the truck died again. The dealer had the truck for another week. I was told that the #6 fuel injector disentegrated somehow and put metal into the oil lines. The oil pump sucked up some metal and they had to replace the oil pumps and the #6 injector. Friday night I get my truck back and load up to go to Lucerne Valley and 5 hours later my truck died again. This time I didn't take it back to Palm Springs Ford but to Fairview in San Bernardino. The tech there said there was still metal in the lines and it blew the oil pump again. For a week the tech replace every part that had oil running through it. Truck has ran great since. It seems like this is a problem with these trucks.

Questions:

If I am going to be doing some upgrades Turbo back exhaust, Intercooler and SCT would it be wise of me to upgrade to an A/M fuel injector? I don't plan on going crazy with mods just try to upgrade to improve towing and MPG's

Has anyone else seen the problems I had above?

Anyone have a reason why my gas mileage sucks? Stock truck. Could it be the 35" tires?

A/M Injectors are just modified stock injectors. No better or worse reliability wise. Exhaust, Banks Intercooler and custom tuned SCT would make you VERY happy, BUT will most likely void your warranty.

 

Yes larger tires will effect the mileage. Just how bad is bad?

 

that's what I have been reading about the warranty. but you got to pay to play

 

10 around town. 14 hwy. 7 towing

 

Mileage really depends on how you drive your truck.

As for performance mods, look at it like this, coolant filter, bypass oil filter, gauges, exhaust, SCT XcalII, fuel line crossover minimum, or fass fuel system, head studs, fluid damper, 165mm compressor wheel, larger injectors (which carry a 2 year unlimited mileage warranty) In that order. Depending on what you wish to do with the truck from there, maybe a suncoast extreme duty tranny kit.

 

thanx for the list. I have been doing a lot of searching and reading before posting anything and have found similar lists.

The truck is my wife's daily driver. Just picture a good lucking busty red head (natural) driving a red F250 down the road. Daddy like! So her way of driving isn't racing around town.

One thing that happens when I am towing with the tow mode is on. If I dont' get the speed up to 65 the tranny will never down shift. I try and drive 60 down the highway while towing and if the tranny never down****s I take off the tow/haul mode to force the tranny to downshift. Will the tunes on the SCT fix this?

 

Yes and No. The tow haul mode wants the engine to achieve a higher rpm before shifting to keep the engine more in the usable powerband. I only use tow haul when coming to a stop, for the engine braking capabilities. Matt will be able to make the tranny shift anyway you want if you get a SCT Xcal.

 

Question:

What I have been reading about the FASS it is an inline filtation system that keeps a constant fuel PSI. If I get the fass do I still need the crossover? And after reading what a fuel line crossover does I am thinking the answer is yes. Even though you have an upgraded fuel pump the rear injectors can still be starved for fuel. Am I right or am I missing something?

 

The biggest thing the FASS system does is remove trapped air in the diesel fuel. Yes you would still need the Cross over fuel line kit, or you may consider a fully "Return regulated" fuel system if you are going to spend the money on a FASS system.

 

Blackhat,

I have been thinking and I have been reading other posts about not needing an a/m air intake until you want to go above 500HP. And out of curiosity what a/m air intake would you install. If all the a/m air intakes don't filter as good as stock why would you risk installing an inferior intake when you go above 500HP?

 

I have not followed A/M air intakes enough for the High Hp applications, and would talk specifically to Matt (PSD 60L Fx4) at LIPD for his recomendations. That being said the AFE Cold AIS Type Si or the AFE Stage 2 Cold AIS Type Cx with Pro-dry S, has a pretty good following.

An internal combusion engine requires a certain amount of Air for its Cubic inch displacement. When you start to increase the Hp & Torque of an engine with larger injectors, turbos, tuner fueling parameters, nitrous, water/meth etc you start to require more air for the extra fuel to burn properly, above 500+RWHp the factory OEM Donaldson system does not flow enough air for the modifications to produce above 500 RWHp. Depending on the amount of Hp & Torque a race motor is making, you get to the point that on the track you run no filter at all, as you want the most air possible and blowing an engine up is much more likely than worrying about a little dust ingestion on the tack.

Hope this helps

 

Yes it does. I understand that a lot more. The mods I plan on doing won't take me up there anywhere close. But I am sure what a lot of people say and they just keep going, and going with the mods.

Thanx
