SCT Lock 1-2-3

need help with my trans tune on my stock sct files. I'm running 50 hp with lock in 1-2-3 the truck takes off alot faster so I would like to keep this lock in 1-2-3 but it shifts funny. not really getting on the throttle hard it seems like it shifts fast to the next gear than defuels after the shift has ended, the truck shakes a little then gets going again. Besides custom tunes! I would like to solve this. It does in on every shift all the way to fifth gear. Increase line pressure or increase MPR when shifting option? Thanks, justin

Get custom tunes, it sounds like you're going to damage the tranny. Why do you want it locked in 1-2-3? You can get a race tune from Eric at Innovative that locks in 2+

Jody at DP TUNER has some good tunes as well, so you have plenty of options.

I have the custom tunes that were put out on the internet by spartan tunning, but the tow tunes look like they throw out to much black smoke/fuel.

Those aren't custom to your truck and needs, they are 'generic' custom tunes. I don't like how they shift on my truck, used to run them, but back to stock now until I can get real custom tunes.
