Sell one of the tunes and try Cobb and report back to see trims.

No its not possible to log LPFP or HPFP pressures with the procede as far as I know. You can with Cobb though.

You can log high pressure fuel sensor with the PROcede, but the data is in voltage and i cant seem to find the correlation. I'm Hitting a fuel ceiling as well at 15 psi on the aggressive maps with OL fuling at 100% however my trims go from +35% to -25% in the same pull....

The units are Voltage 0-5V. and from what I've gathered data wise its ~1.3V at 720psi (idle) so that would come out to a ~550PSI/Volt if you assume a linear scale... which may or may not be a good assumption. The OBDII scan tool updates once every minute or so when the procede is running so i have no way to test the scale.
