Needed to adjust the Port Injector BRZ scalar down 3% to balance up the PI with DI.
Now getting pretty well 0 ltft (+/- 1%) except for the first couple near idle about 3% variation with large changes in intake air temps.

After running a slightly modified version of the port injection ratio table(0% in .20 loads) with 5% lower value on the port injector scalar, my fuel trims are still a bit high at the .30~.40 areas where its' running 70% port. Though this is on my new maf scale that was dialed to 68*f/20*c. I've decreased the value to -6% lower than the stock value and will see if that fuel trims will go down a bit more.
