    What was going on?!?

    Today while I was at the track on my 7th and 8th runs I think for some reason it seemed like my truck was hitting the rev limiter for a split second before it made the 2-3 shift... it only did it those two times and then quit....
    Anyone know what was going on?

    Could be the injectors cutting off, MPH not letting the trans shift, rev limiter close to the shift rpm... Could be a number of things. Give Allen a shout and go thru the runs with him. You have any way to log at all?

    6L80 I believe, maybe 90. I don't think it's the trans, jet something weird coin on in the computer somewhere I guess
