    really wacky inj pw and air fuel of all sudden

    i am try to figure out what happen to my log - i was messing around with the tune to fix a tip in issue - got better and went to do a WOT log - see attached - this a boost twin turbo coyote and it should not be running at 1.22 AFR and 35% INJ Duty cycle?!?!? I can tell you it runs smooth to redline other than this tip in I am messing with - fuel pressure is strong.... what doesn't make sense to me is the ultra lean condition and very little injector cycle being commanded??? I changed out my HP dongle with a buddy of mine... same thing.... so I put it on my bone stock 2018 F150 truck - WOT - 13% inj duty cycle??? but AFR is around .88.... but that inj cycle seems off too... looking for thoughts on why my twin turbo setup is oddly showing this log - I would have melted a piston by now - not to mention it wouldn't be able to make 10psi this way - it would be breaking up like crazy!!

    thoughts???

    I am think my laptop is bad??? or I need to reinstall the scanner???

    help!!
