Ok guys I have been beta testing the tcm tune from h&S and so far i am really impressed with it and have seen no problems what so ever. The shifting is so much better then stock, the tc locks up alot sooner in the gears and stays locked up for me. I do not get the annoying downshift anymore that I used to get. They have changed the rpm to where it goes into 6th gear, which has eliminated the shudder in my truck i do not get it anymore. It shifts alot harder and seems to hold the gears longer then stock on wot runs. The rpms stay right up there on the wot throttle shifts in the upper gears and rpms really dont seem to drop much at all like they used to. And it seems to shift alot faster, then it did before, not faster in the rpms but faster from the time it takes to shift gears if you understand what I am saying. Tranny temps dont seem to wanna climb after alot of wot throttle runs like it did before, mine never got over 180* and was about 170-180* the whole time, didnt seem to cool it down anymore then it was before, but keeps it from heating up more then it was, using I was over 200* doing wot runs. The truck pulls alot harder now especially on the 120 setting, and my rail pressure still holds at 26k. Running the 225 setting it still pulls harder but it sucks my rail pressure down even farther then it was, its going down to 18k now, and on a good wot pull on the 225 setting i will trip a cel for low rail pressure which it wouldnt do before, but is now expected getting more power to the ground. If I remember anything else, i will post up and try to get more feed back as I get more miles on the tcm tune.
That poor little 68RFE just doesn't stand a chance
