Excellent, Ill give that a try but I only lockup in 4th so Ill set my mph higher. Are you using a stock stall?
yea Stock stall speed converter from Transstar. Its a BU52 part number in a 2500HD. Locking it up in 2nd gear at the right time makes it pull heavy trailers very good. But i dont try and lock it up unless TCC Slip is less than 500 rpms.

Good thing I emailed them. They responded with:
EFILive does not allow you to roll back or downgrade firmware.
Please supply the cax you are trying to add and I'll have one of the engineers take a look.
"
I sent over my files so hopefully they can help.
Good to know on the firmware for future reference. I am also glad you emailed first.
I see they also were very helpful in getting your file fixed up!!! That's also great to here.
