Starting tomorrow, I am going to start the week long process of changing every fluid on this Beast! (Work vs play ratio + doing this while TDY without my tools :-) (Have to rely on the self help center))
** All my questions come from reading way too much and getting confused as to which direction to go!
1- If my mod goals were centered around MPG, (no major towing yet) what would be the best path? Is it feasible to reach for at least 20 MPG? The guage showed 12.8 MPG on the 130 mile drive home yesterday which is 4+ less than expected.
2- I guess I just do not know the benefits I would gain by all the DPF delete options. DPF delete pipe only vs DPF + CAT delete vs Turbo back DPF/CAT delete. Does the $300+ difference for the Turbo Back option gain me anymore MPG? Ok it will breathe better but how much better?
3- Programmer...Now this seems to be an opinionated topic!! But which tune will benefit my goal? I know, I know...I did not buy this Beast for the MPG but it would be a bonus to get to at least 20 MPG! I have been leaning towards SCT Livewire 9621 based only on reviews then I read about the Mini Max ($$$)
4- Air Intake: can this be phase 2 of my mods or is this a priciple player in my stated goal?
5- Is there a cost/benefit by using Motocraft fluids or are the aftermarket products better? Oil/filter, Tranny, Fuel filters, coolant, Diff lube?
OK that is a great start for my first post!! I have lots of questions and there seems to be NO real diesel performance shops in the Augusta GA area that I can find..:-)..If anyone knows of one in the Augusta area or the Nashville area, it would be greatly appreciated..
Opinions are ok but facts trump everyone!
1- yes its possible if you spend $$$$ on the delete , tuner and air box. 12.8 is terrible .
2- you dont need the down pipe, just get a dp back delete. it is plenty. a full delete will offer the best performance.
i run a full straight pipe with a 4" aero turbine muffler. . no restriction.
3- you get what you pay for. sct - not the best
4- cheap , and important to efficiency.
5- no noticable gains from fluids, especially not coolant
it all comes down to the delete if your looking for large gains. generally the higher HP tunes give the best MPG . but until you let it breath and get rid of the regen you wont see huge gains.
