strange transmission stuff

So I'm running the spartan 210 tune, when my truck shifts into 5th gear, the rpms drop pretty low, and the turbos sound as if they are emptying, and this low grumble/vibration noise comes from under the drivers seat. When you back out of the throttle (only in fifth gear) a little too fast it kinda jerks, when you let it out slow it doesnt do it, same as when you get into it. I've never tuned it higher in fear of screwing my transmission over. Anyone have any clue about what I'm talking about?

It did that for me when i had the 210 tow tune. I wasnt happy with it, go up to 250 and 275 they are much better tunes. The tranny can handle it easly. I run the 310 as my DD and it is great. I dont get into it so no worries about the tranny

have you done the new download for the tunes? Download the 300 and see if it does it. You will have do a tranny relearn after downloading it.

I think you may be referring to the TQ lock up, with the turbo's and rpm.
Not sure about the grumble/vibration under seat though..
