well, a couple of guys that are running MS are working on taking over the trans control as well.
but you can raise the shift point, i know there are guys running up to 6000 and 6500 rpm, but even then... you gotta play with it. the tune might say 6700, but it really shifts around 6500. it's not totally... exact.

The hydraulics of the transmission will dictate when/where/how it shifts.

the 545 is behind the *.7 engines I believe (I know 5.7/4.7 for sure, I think 3.7 too) and are full electric control I believe.

Yea, the 545 is a multi-choice gearbox.
The SCT gives you tuning freedom but the SC Flashpaq will move your shift points.
1st 3.00:1
2nd 1.67:1
2nd Prime 1.50:1
3rd 1.00:1
4th 0.75:1
5th 0.67:1
