If you are asking can line pressures be manipulated, the answer is a qualified yes. It cannot be done strictly mechanically, because the TCU will either learn it's way around the mod or issue a DTC. No disrepect, but properly tuning a clutch to clutch shifted transmission is way more than adjusting pressures.
I think the biggest difference with the xHP is the control it gives the operator. Second, if your tuner isn't modifying the calibration of the TCU, then they may be implementing a band-aide fix. Finally, there is something bigger going on here. This started as a community led effort and we are fortunate that someone has championed a service that essentially makes TCU tuning (not the flashing method) open source. That means things aren't secrets - the situation are have found yourself in.
