My duty cycle was 88% at the top end, and still going to 14:1+ afr.
The mystery is my plugs, they are all over the place in color. Cranking pressure and leakdown is fine. I think I have an ignition or injector firing problem, some of the plugs are sooty black and some look almost new. The strange thing is, they are not companion cylinders (waste spark/phase sequential strategy).

Sounds like you have some serious issues there. Remember your averaging you O2 from 4 cylinders (some fat/some lean) don't expect to trust that.
Get those cylinders running closer, then you can begin to fuel accordingly. Those 55's are good for 650hp at 90% DC and BSFC of .60.Dennis

For base runs at NRE, the setup was a TEC3 controller, 83lb injectors and a F-2 blower with absolutely no problem from idle to WOT. 83's can support 1000+ hp with various combinations.
