This is the same tune it is 45 degrees after i drove the truck 90 miles tuesday and today it looks good ?

I'd be happy with that. Bad fuel or something before?

Idk im installing my fass 150 tomorrow and deleting the factory fuel filter so we will see how much better it is

Ok lift pump is in and holds rail pressure at desired and drives much better on the top end ...BUT i left my negative battery cable loose when i went ffor test drive and now im getting a v0100 lost communication with ecm/pcm ??? Where did this come from what does it mean ...truck runs fine

It means you had low voltage and it likely caused a drop to the ECM. Clear the code, tighten the battery connections and see what happens.

Did that and cleared it 3 times and it is still there no CEL some could it be one of those that takes a few cycles of the key to go away ? It doesnt seem to be an issue other then bugging the crap out of me lol

Where did you get power for the lift pump?

Quite possibly requires key cycles or EFI Live/Tech 2 to remove. Need to see if it's an active code or how many times it was set to be sure the problem is gone.

Got power for the lift pump from the red power box used for jump starts and ground is bolt on motor and i still need a good key on ignition source im using the parking lamp fuses and i need a better fuse thats not controled by lights
