Guys .. my 2000 v-10 doesnt seem to have the get up and go lately... true 180000 miles on the clock, uses about a quart of oil between changes. truck seems to lack power when pulling a slight hill, i have to get in the gas a little more. i recently did tune up plugs, installed timeserts to avoid future problems with plug blowouts--cleaned maf, new pcv valve and hose(ford pcv valve).also new air filter, but mileage never changed....still 11.5. would have figured that it would go up SOME after tune up guess i'll change out the fuel filter and check the cops, although i replaced two during tuneup.any other ideas let me know ......thanks Britt

 

I would suggest cleaning MAF and taking off and cleaning throttle body as well just as good PM stuff.

 

thanks....will do you think maf is still okay withh high mileage? truck hasn"t thrown a code yet? just want to get as much out of the old girl as i can.....

 

I would think the MAF would be ok still. Also when cleaning the MAF I recommend disconnecting neg bat terminal before hand.

 

Thanks....have thought about a tuner for this truck, but wonder if i would get any help with the miles on it? on a side note, i see you have a dyno ...i have an old 69 volkswagen that im semi-restoring, need to bring it up and see how much horsepower the new engine i built is making as compared to the 6.8!! thanks Britt

 

your welcome, That 69 volkswagen would be fun. Our 99 has 197k mi on it and runs better tuned than in stock form...

 

i'll have to get in touch with you when i get the bug finished...my truck is bone stock now, even rams horn y-pipe what improvements could i expect with a tune? other than mileage?

 

Hey Britt
see here for tune related info Got a V10 Ford F250/350/450/550?

 

Definitely change the fuel filter, they are a 30K miles maintenance item. I changed mine at 20K and noticed a big difference.
