What is your injector duty cycle? I can imagine it super high with the 20g and 10lbs of boost. I can't view your map though since I don't have the Ultimate. I have the blue.

cant remember off the top of my head but i know Kenny maxed them out at 14psi, so we backed it down to 10psi.

so it should be 70-80% which is all the higher i wanna go. running as rich as it is im sure im closer to 100% but when tuned right it shouldnt be that high.

Intresting, cause i run 750cc's and they are in the 70-80% range at 12lbs, so I would think 550's at 10 would be pretty high if not maxed.

it depends on the target afr, low 11s afr on 550 cc are like 80-90% on the gt30.. but im not sure about 20g, but if you have an aftermarket fuel pump it will be lower
