u7165 fu mileage loss with updates

Post by machinegun0331 »

I have a 05 Ford f250 6.0. I started out with v9r10 and worked great fuel mileage was up to 24 highway and in town no less than 17mpg since all the latest updates power seems to be there but mileage went way down highway is around 17mpg and town is 14mpg, I had my truck looked over and all turned out good. Currently running latest update v9r14

What level on the tuner did you see the gains from on the 9r10 versus 9r14? I will look into the changes for that level.

10 MPH?

Thats over 100 HP at your weight....something is not right, I'm going to go out on a limb and say the truck has an issue...fuel filter, injectors, EGR?

Also with the 9r14 I noticed a difference in shifting, nice firm shifting, but huge difference in rpm range when it shifts its shifting around 4500 to 5000 rpm

One of the shops gave me a newer predator it has lots of power now, just need to see about fuel mileage, they said even though mine was only a year old sometimes they find with the updates you have to have a newer predator. So they took my older on3 for Exchange of the newer one.
