Mileage?
Okay, I am interested in a 1999 Ford F-250 4x4 5.4L XL, and I was wondering, if I purchased a Superchips Flashpaq 1865, how much would that increase on the gas mileage?
Thanks

I'm not sure on how much but the 99 models have less power then the "PI" 2000+ model years. I would look for a 2000+ if it's in your price range. I'm
Sure Someone will chime in on the mileage but my E350 with the 5.4 gets about 14 highway and about 12 city

My chip has an economy setting too. Doesnt increase mileage much.

Yeah I don't trust tunes' claims of better mpg. From my experience my truck gets better performance but the mpg stays relitively the same. My friend with a 5.4 3v claims he gets better mpg with a superchip but that is all based off of a dash mpg indicator. I think that if you do get the truck get the tuner you want and then hand calculate the average fuel milage over at least 4 tanks of gas. 4 tanks without the tune then 4 tanks with the tune; then you would have a good idea of how much fuel economy you got.

If all of the claims for better MPG were true, you could have a 50mpg truck with all the BS out there...

Lucky anybody responded to you at all. If you're fooled by all the claims you read then I've got some ocean front property in Central Kansas I'd like to sell you.

There are some things but few are worth the investment. Keep up on tune ups, get an SCT tuner, and maybe a few other things.

Improving MPGs is not easy to do with a gas engine. If there was a magic bullet, then the OEM's would be using it. All mfg's of aftermarket performance accessories claim improvements, yet none consistently and reliably deliver.
