    Rough shifting after Revisions

    Heres the deal. At WOT my truck shifts hard into third. Not firm, it feels like it is slamming into third and I can hear an audible thump. I have had two revisions for this issue and although it seems a little better it is still there. The weird thing is it only does it fifty percent of the time (When warmed up). I thought maybe my PCM needed to learn the tune but it has been a couple hundred miles. My question is this; Eric is a busy guy and before I bother him for another revision can I fix this myself through the adjustable parameters of my intune? Right now it says my shift firmness is stock, which i find odd because it definately does not shift like it did when stock. Thanks for any advice.
    On a side note the best 0-60 time I can get is 7.1 seconds. I know I know its a truck. But this is one way I can compare tunes. Does this seem slow for a 91 tuned truck?

    My Let shifting was extremly hard shifting into gears, after 10 revisions it never got any better. You may have to tell him to put it completly back to stock settings for it to not bang so hard.

    Its only third gear. My diablo tune says the shifting is stock. It will only let me firm up shifts, it wont let me go any softer.

    I just use my app. I know there is a margin of error but it is one way I can compare tunes.

    Stock they are under 7 seconds, the tires shouldn't make that huge of a difference. I had Erick dumb down my shifting a little bit as well as I had the same problem. SSI and Unleashed tend to have the smoothest part throttle shifts at least in my truck. It is all in what you like, but on a 91 tune you should be able to do better than 7 seconds IMO.

    How are you launching? With all the torque your now making it can be hard to hook up, takes a little practice.

    My LET tune used to slam my 2-3 shift really hard anytime above about 50% throttle. I asked him to turn it down and it's a bit more mild, but it doesn't chirp the 1-2 shift as easily anymore . Oh well, can't have both I guess.
