Like the title says I’m looking to see if any of the canned SCT tunes lock the torque converter up earlier than stock. Truck has so much power, but I feel like a lot of that is lost with the TC being unlocked since the truck shifts into OD around 35mph with lock at 45ish mph. I do have the SCT BDX (newer X4) with a trans only tune but want to lock it up in 3rd gear and higher. Anyone have any info on this or do I need a custom tune? Any help is appreciated, thanks!
