I am tuning a 2015.5 and starting to make some power. Every time I floor it the fuel filter life goes to 0% on the dash (about a 120hp tune). Is there anything that can be done to make it less sensitive? I can unplug the sensor but would rather not have to do that on every truck. Im sure someone has ran into this before.

Your draining the rail, watch your logs, either pull some full out of it or get a lift pump.

Why am I not getting a P0087 if this is coming from low fuel pressure?

My LML doesn't either, drains the rail then fuel filter life goes to 0%. It's not the same as the older trucks.

Yes that’s what this one is doing. Thanks!

Shut the fuel minder switch off. The only thing that will set a code is the 0087 as you know,
It does not take much to trip that stupid switch, add a lift pump as stated.
