couple of mod questions

[02 f250]

i have a 02 with 128,000 on it bone stock the fuel mileage is killing me and my goal is to gain some more mileage and a little more power with out spending a ton. So far i did the diy 6637 and next im going to do the muffler delete i dont think by putting a full system on it is going to make that much more of a differance i have been researching chips and i think im am going to go with a php tuner. this question prob has been asked before but with the chip am i going to take away from my engine and trannys life and cause premature failure to these? my truck still has a powertrain warranty for another 80,000 on it and if i were to put a chip on is it easy enough to take it out so no one would no i had it on the truck incase something major was to happen ? hopefully someone can give me there .02 cents on this

the engine can handle it fine its been way detuned. these things can take alot. the trans is the weak point. i suggest better cooling and a valve body to start1

A John Wood Or BTS valve body are probally your best bets there.

^It does? My old late '99 6spd never got below 17-18mpg city beating the **** out of it. Normally I got about 22mpg city though. I dont know what the heck you guys are doing to get that kinda mileage...

You also have a 4X2 thats has less wind resistance and less rolling resistance and weighs less than a 4X4. Elevation plays a big part in milage also, the closer to sea level you are the denser the air which = more oxygen and will give you better and more complete combustion.

Does anyone offer a tuner the goes threw my ob2 port that has custom tunes and also tunes the trans. I dont want ford to void my warrenty if something breaks beacuse they found evidence of one being on the truck

[big sig]

Use a custom tuned chip. PHP, TW, Beans, Gearhead, DP are what a lot of people run. I have a php. I really like it cause its switch on the fly and all you have to do is physically remove it to take it off. Takes 30 seconds to remove.
