I had someone tell me the other day that he put a chip in his '00 F250 w/ V10, and it increased his gas mileage 4-5 mpg. He also said that he used 89 octane instead of the 91-92 octane, and didn't have any knocking or pinging..

Has anyone else experienced this? I don't know exactly which chip he put in it, but I've been looking at the Superchips MicroTuner, and wondering what difference it will make in the MPG area..

With the price of gas going up, and driving 100 miles each day, I'm looking for anything to help...

Thanks in advance for anyones input!!!

 

4 to 5 MPG increase is very doubtful. If your check all the boards and forums most guys maybe see 1 to 2 mpg increase when installing a chip or using a microtuner. V-10's in SD's normally get 10 to 13 mpg depending on cab style, tires, gears etc. A 5 mpg increase on a truck getting 10 miles per gallon is a 50% increase, NO WAY. Was this guy also trying to sell you water front property on Three Mile Island in PA. ?

uh...well...since you mentioned it, he said the view is great from the shore!!!!!

I figured it was too good to be true, but I figured I should ask.. I know the best way to get better mileage is to keep my foot off the accelerator, but everytime I try, some D%%GE or CH#$Y pulls up and has to be reminded why FORDS RULE!!


Thanks for your input GAV10...

By the way, did you have to remove your spare to put your auxillary tank in?

 

bddo,

Aux fuel tank sits in the truck bed, under the tool box. I only use it on long trips while pulling my travel trailer. With the short bed trucks having a 29 gallon tank, only 24 usuable non-harpooned, I only had a 200-220 mile range. The extra 25 gallons can get me to the lake house, or home to the parents, without stopping.

i just put reprogrammed with the Hypertech programmer III...it give you an option of running 87 or 93 (91 in my area)... i'm running it on the 87 but noticed only a small difference in mpg. it did stiffin up the shift point, and at half tank i can the tires up out of the driveway....

rollnxl,

thanks for the feedback...

I am curious though, are there issues with switching back and forth on the program from 87 to 91/92 octane and back? Does this cause premature wear on the engine?

Thanks.

 

Hello, I used to be in here, long gap but Im back. Ok, for over 2 years I, and others even shops have been trying to find a problem on our 1999 F250SD 4WD V10. It randomly wont shift right, Speedo wont work, runs like it's on 2 cylinders rich as can be, the check engine light goes on, the code cant be read and communication to the Computer is broken when this happens. I have been stuck in this truck, took a long road trip in the beginning, 12hr drive there, all was well, 24 hour drive back because this problem arose. After trying a billion things, we finally decided to replace the computer. Low and behold, there is a superchips tuner on this as it was bought in CA. Plus, there is a Truspeed computer in it also. I cant say it is at fault just yet, but Im removing it and putting the computer back in to try it. Ill let yuou know but you cant imagine the nightmares we have been through with this truck, and shifting issues, and random power lows, and then it will run p[erfect for 2-3 Months, then its bad again completely random. I just wanted to share this with anybody considering this programmer, but I will post back when I know for certain it is the problem. After all we have been through with this truck, I will not run a programmer again except a plug in tuner, so I can adjust things myself.

 

I just realized this is a 26 year old post. Sorry about that.

 

only 23 years old now, best to start a new thread
