5.4L Gas Milage questions
Thanks. I did not know about high flow Cats. The local mechanic said he had gutted alot of Cats in Chevs but not that many 5.4L Fords around, all Diesels. Seemed like a good idea as there would be no restrictions.
The truck is running great and now that I have driven for 700km, the milage is definately better than before the upgrades, power is very good as well. Truck used to shift out of overdrive constantly even with a strong headwind. This does not happen anymore, very happy bout that.
Anybody know which is the best Tuner for the 5.4L, and will it hurt my transmission?
