Are you building too much rail pressure? I would get a weird fuel limp when I was running the LBZ reg.
Never a code or CEL, just lost power at higher rpms.

Mine was always at 92mph....part throttle/wot didn't matter. Acted almost like I left off the gas and got back in it.
Betting its not that.
Have you logged your FPR and TPS? Maybe a dead spot in it.
Just throwing out ideas to check.
