So I went in with a buddy on HPtuners and figured I'd play with it on my truck a bit. I used the credit and unlocked it to my vin then realized everybody hates the "blackbox PCM" that it has in it.

All I'm trying to do right now is firm the transmission shifts up a bit, but coming from the older stuff not sure where to begin. And I'm not talking neck snapping shift kit shifts, just a little better than stock.

I'm really having a hard time finding much info for this truck with it's redhead stepson of a blackbox PCM.

Auto shift properties > Shift Time
I planned on just cutting the stock times in half.

Auto shift properties > Shift Pressure
Should I just bump up the max pressure a few (stock is 90) and scale up the Shift Pressure Upshift tables a bit?
Some people seem to rather leave the pressures alone and just remove a little bit of torque management in the trans. It's a tired 4l60e, so I don't want to kill it. Just make the truck a little more fun to drive.
