Your problem may be the 50% barrel setting, that is way rich, we set our valve at 18% using a cylinder leakdown.
We keep track of the barrel setting because it can change after we pull the injectors off the motor. I like 18% because it lets my motor build engine heat, and the hotter we get the engine temp on my alky burning motor the better it runs. I try to get the engine temp to 180° to 200° just before staging in my all iron SBC with water.  150° to 160° with no water. BTW on  dyno testing we found the SBC would make 20 more HP using water in the block & heads. WE think because, ya the more even temps is part of it, but the water gives the cylinders more support and also cuts down on harmonics, there by getting better ring seal, and that's where the extra power comes from.

Have Fun
