F250 turbo? Do you mean one from a Powerstroke? You sure that's gonna work (i.e. does it have a T3 mounting , how do you plan to connect it to the downpipe?)

Anyway...as long as you are still on the stock computer, you have to keep the stock 35 lb injectors.

And your cat has nothing to do with your gas mileage, or your gas gauge :screwy:

I think you have a different definition of "no problems" than most then ;)


Without some major tweaking, the stock ECUs won't run well with injectors that big..

Sorry, I misread your post.

Anyway if the gas gauge is all wrong, either it's the gauge itself, or the sender for the gauge. I couldn't tell you which one though.
