Yeah there is a Flash tutorial in the Help section on this website and in the HPTuners software you installed on your computer.
Here is the link. To get to here you go to Help->Getting Started Tab->Demos->Applying 2-Bar SD Enhancement.

Basically what you do is copy the entire row in the 105 kpa section and paste it in the 210kpa section. Then you multiply the entire row in the 210 kpa section by a specific number (read the tutorial for this), and finally interpolate all the data between 105 - 210 kpa. If you can't figure it out on your own reply back with the attached hptuner file and I'll see if I can set it up for you.
