So my buddy has a 2013 with 68RFE he was running the rame003b firmware and was happy with the shift firmness and torque converter lockup felt good. We updated his tuner today to rame006b(latest update) he says the trans feels terrible now and is seeing much higher torque converter slippage.

He is using the "stock transmission" option under transmission on the settings which is supposed to up the line pressure and firm up the shifts. He says it feels terrible now and wants to put back the original files back in the tuner. (Luckily I made a backup of the whole memory card)

Any ideas would be awesome.
