Raptor thinks it's getting low octante fuel

[Nex]

Does it have a custom tune or just an off the shelf one from Cobb? Goose will get you sorted out.

I'm working with Winfield. He's been great so far, and patient. So it's a goose tune, second tune. I didn't know the issue when I bought the tune but I bought it because the truck felt sluggish.

Before ECU reset.
ECU Reset.
Car running for a few min and moving from the pump.
After I got home back to 88 octane.

I had a suspicion for while the gas station i always used was low octane then i switched stations and timing came back up. i steadily see 2+ deg adv with only -.50 deg timing correction.

Also colder air and very low density altitudes as i write this -2000 ft in AZ will drop your boost a little because air is thicker compared to higher temp air .

I run Arizona 91 octane and use boostane bring it up to 95 on mix chart. This is 55 deg air this afternoon . Cobb ots stage 2

This morning 30 deg air and -2000 density altitude

I would be changing spark plugs gap down to 0.028 before anything else if your fuel is same other raptor is using
