2007 Ram U7137 1st to 2nd prime up shifting?

[LeePeterson]

Hello!

I just put a 91 predator tune on my 2007 ram and at part throttle it's up shifting 1st to 2nd prime. It bogs a little on acceleration I have to manually shift to 2nd then it takes off great. I'm using the latest crom 14.

Thanks for any help.

shift pattern should not be changed, did you add a bunch of throttle boost?

I'm at 20% TB. I've been paying more attention too it now, maybe it's the way the factory shifts too. It's not going 1-2nd prime it's going 1-3 when going around corners and letting off throttle, then coming out of the turn it downshifts to 2nd prime. Can a CMR tune raise the 3rd gear shift rpm higher at less the 10% throttle.

Thanks for the reply!

yeah, my understanding is it can only downshift to 2nd prime, it never upshifts into 2nd prime.
Yes, a CMR tune can adjust these items further for sure.
