Frank, it's 12:1. If I ever need to rebuild it, I am going higher. I run VP100 in it anyway for insurance (stock headgaskets). Probably would to 14:1 some day...

Try increasing the Inj Offset v Bat V and the Inj. Offset v PW tables.
140 VE% is pretty worthless. Ultimately may need larger injectors.
Based on your results, 30# should give you adequate headroom in injector DC.
