May have found some explanation about the TCC slip and settings in the tune. I dont have the tune open in front of me, so explaining from memory

Not sure why it was done this way, but the tune has the TCC regulator offset set at 80 psi. It appears that stock is around 20 psi...

I had been wondering why the TCC desired pressure caused slip at the stock setting of 114 psi, when others with a similar setup reported no slip. When I was on the 4.13 pulley, the pressure was increased by the tuner from 114 psi to 200 psi and slip went away.

Again, not sure why regulator offset was changed... but if the regulator offset does what i think it does then the 200 psi is really just 140 psi. In other words, the current 80 psi minus stock 20 psi means all the numbers are inflated by 60 psi in the tune. So 200 psi - 60 psi is 140 psi. And when the tune was originally provided, the value of 114 was really 54 psi.

The values in the apply ramp were also hugely inflated over stock too. Probably to account for the increased regulator offset. Ill try to remeber to post actual table data later.

Anyway... it just didnt add up to me leading me to believe that at 200 psi of pressure i was still getting TCC slip. Made me think it was a mechanical issue....

Who knows maybe it still is..... but after i compared some other tune info... it makes more sense that the TCC regulator offset is making those pressure values appear higher than they actually are. And if i can verify that, then i feel more confident in adding some addl pressure to the TCC desired pressure to try to get full lockup.

Would be nice to see an actual tune file where this is all working on a similar setup. If you are willing to share, PM me.
