In the tune? What are you trying to do? Are you saying it won't let you?

I believe lowering that value actuly increases the overall pressure in the tune.

It does, it works hand and hand with the shift pressures table.

You do know how that table works right? If not there are other tables that effect it and may not allow your changes to do anything. What's your max commanded line pressure value set at?

I've just began tuning gas i'm use to large caterpillar motors but anyway, i have the max pressure set to 96, shifts firm like i want shift times seem ok but almost seems as though it hunts a gear before shifting, might just me. were i screwed up is i copied someone else's tune and it's been messed up since. Like i said i almost have it were i want. Hell one guy posted zero out last row of force motor well i can tell you that was a mistake truck went to hanging till i lifted at wot. This is a 05 gmc 2500 hd 4x4 6.0

Post the tune.

Did you license the PCM in order to make/save changes? Or is it that it just doesn't lower when you try?

Post it and I'll see if I can.

Yes i have a license. Through hp I pretty much have it were I like it,i just need to soften the shifts up some,it's pretty harsh. I added5 to the whole table exept last row which is back to factory settings works better that way in force motor
