Just purchased a '91 F250 4x4 that is in immaculate condition. I will be using it to pull livestock trailer and haul feed. I am wondering if I can improve mileage and performance with one of the "chips" on the market?
Thanks,
Gary

 

Thread moved to the 1987 - 1996 F150 & Larger F-Series Trucks forum.

 

Off the shelf chips for this vintage truck is a complete waste of money and time.

 

Thanks for the information.
Gary

 

what motor do you have? There are a few things that can be done to improve mpgs and power... Do we get to see pics of the new aquisition? We love pics!!!!

 

The truck has the 5.4 engine and 3.73 rear end. I am not computer enough to post photos. It will be used as a ranch truck but is in like new condition.

 

A '91 with the 5.4? They didn't come like that in '91. It's either a 5.0 or 5.8 if it's a small block V8.

Chips for an otherwise stock gas engine from the early 90s and late 80s are pretty worthless. If you want a little more power you're better off messing with timing a little bit and upgrading your ignition system

 

They also didn't come with 3.73 gears; so it looks like someone's done an engine and gear swap.

Gary...
Saying that it has a "3.73 rear" has me worried? Does it not also have 3.73s in the front? If not, you'd better not be using 4wd until you get some.

 

Dummy me it is a 2001 model with the 5.4 and 3.73! What is ten years when you have been around as long as I have.
Adios,
Gary
