[PRICELESS]

Its a brand new 2012 gmc denali dually . I had the same tuner on an 11 2500 and i got these messages on that truck also . It has recent update i think and cant understand whats goin on. When you scroll through messages it says 0% fuel filter .....

Same thing happened with me, loaded wild with DPF present and All didnt even drive the truck and it saying the same thing 0% fuel filter

If you reset after loading the tune will it will it show 100%? Or is it stuck at zero?

Im curious about this too, I'm getting the same message. I just installed an HS yesterday with the DPF present until I get my exhaust and intake - Running "wild" tune.

Does anyone have any more info on this? Is it worth changing the filter in a truck with 2k miles that is showing 0% filter life? I have an airdog2-165 waiting to be installed, I figured I would run the stock filter along with the lift pump and replace the stock filter while installing the airdog.

This message after tuning it is normal because it erases the life during tuning. After tuning reset it then it should be fine. If your life was lower before tuning you should probably replace the filter and then do the tune and reset it. I have done prob 20 deletes with h&s and every time after the tuning is done the fuel filter life is at 0
