Heres my high speed fueling (top) and timing (bottom)

This is before I changed anything, as you can see, the fuel tables were PUMPED in the area that were showing the lean condition. The highlighted area is the highest the car sees.

This post was a great read, glad you got everything worked out.

Are you running normal 91/93 octane. There is no way you can max out id1000 or a wallbro 255 on straight pump fuel. Generally on stock fuel pressure 1000cc injectors are good to about 600whp on gas 93octab/c16/race gas and about 470-500whp on e85. A wall to 255 maxed out at about the same or a little bit higher than 1000cc injectors. Maybe you should start thinking about a return fuel system.

It's "sorta" a return system now with the surge tank, it has an adjustable fpr on it after the pump, before the rail, so if I run out of duty cycle, I can just bump the pressure for more head room. I'm running ~ stockish pressure and my duty cycle is now about 70% at 13 psi, 8500 tuned to 12.0.

The leaning out was caused by faulty wiring, the supplied pinned harness from radium wasnt making a good connection. I repinned it and electrical taped the hell out of it to keep it from moving and my issues have disappeared.
