    Frosty, do you have the timing table you are using for your car? I would love to look at it.
    I am new to e85 and am working on my tune.
    I am starting with a 2005 Comp G timing table and seeing no kr so far.
    My mileage was 300 to the first full tank.
    I went the route of changing the injectors to the following. I may put them back and use your method.

    45.84 46.33 46.94 47.95 48.17 48.22 48.22 48.34 48.44 48.51 48.78
