I have sold my 78 ,so got a little cash to spend on my other ones. I' m going to get new rims for my Excursion to update it. I have about a thousand left over to put into my F-250. This truck is bone stock,except for CD player under seat AM/FM/CASS still in dash. It has 238k on it. It is a work truck,it pulls a #3500 trailer everyday. Stock size tires. I want to improve power and MPG. I'm thinking intake and exhaust,but with that many miles don't want to go crazy. I have a K-N FIPK on my Excursion and they say it could add 10hp for this model. Need some good advise . With high fuel prices maybe, I should just save it for that. Thanks

 

DOWN PIPE, air intake, straight pipe exhaust, TW chip, gauges.

 

forget the KnN, no good. they leak and dust turbos. as for the mileage, yours is just breaking in. id say get a 4" exhaust system (turbo back w/ a round downpipe), a tymar intake (search 6637 filter mod on here for instructions), and a tony wildman chip. then get yourself atleast a pyrometer and boost guage. that shoud still leave ya with a few hundred left over and provide you with both increases in horsepower and fuel mileage. it will also help you in the towing and general driveability aspects.

 

damn! ya beat me 2 stroke!

 

yup. i like bein able to read codes with my superchip though. and i get good mileage. 14mpg around town mixed between my mowing equipment and 16,000 pound tractor and trailer. we have had k+n many miles between 3 trucks with no problems. i wouldnt mind dusting my turbo to get a new one LOL. but, the dirt is bad on the engine too of course

 

x2 of what they said just i would go with a DP-Tuner. But that is all preference.

 

If they were gassers they don't count. its a diesel thing!

BTW happy to help you spend money!! 6637 air filter, downpipe (or full 4" exhaust), pyrometer and trans temp gauge if an auto then a TW or DP chip. Oh yeah trans cooler should be up there too if you still have the stocker in there.

 

all 7.3 powerstrokes. =). 100,000 miles on one truck with the flat stock kind of kn, and 15,000 on dads new truck with the filter off his old one. and 25,000 on mine with an fipk, and 140,000 ish miles with a stock-style kn filter. =)

 

eeewwww....Good luck with that!!

 

turbos all seem fine, with baby-butt smooth compressor wheels.
