    Could you tell a difference in performance afterwards?

    Not particularly but the truck was running very well already. I was having no issues just did not like that 45% and figure $75 was worth it to reset it and see how long it takes to creep back up.
    Idle exhaust note seemed a little deeper and smoother however.

    Good deal. Thanks for the extra info. Good luck with it and hope it helps your mileage too. Sure shouldn’t hurt it

    I think mine is developing the same issue. It still starts but acts like its rich and inconsistent mileage. When the mixture is correct it starts with gusto. It almost seems like its loading up and if I step on it hard it will smooth out for a time

    I am a little over a week since having mine reset.
    No notice in drivability however I am getting noticeably better gas mileage.

    I never calculate mileage as it’s a waste of time because I am going to fill up regardless.

    But I make the same trip frequently that takes my right to a 1/4 of a tank.
    I made this same trip yesterday and I was only about halfway between 1/2 and 1/4 of a tank.

    The reason I think my pump is going is because it surges under load. This is the most inconsistent vehicle I have ever had milage wise and running. One time you step down it screams to life the next time it just acts half asleep. I think this is due to the way they are programmed from the start

    Where in techstream can you check the alcohol density? I need to check mine. Didn't know about this issue before I bought my FFV truck last year
