    Riding the line of the torque tables, maybe try rescaling those and see if you get more.

    I would increase the driver demand a little more in the 79 and 90 rows. Bump torque tables as suggested. Put all your low, high and nominal LSPI back to stock. Increase LSPI high just a little, add 0.1 at a time. use that to control boost and lower to around 230 KPA. It won't take any timing at your boost level. I am at 5-6 degrees @230 KPA 93 octane.
