You can try the following to work around the VAFC add fuel limit..
Use the aftermarket regulator to pump up the rail pressure, then use VAFC to trim the fuel.
but the fact that you're running B20B injectors should not cause any issues of running lean.. It's kind of strange that you're having to resort to such measures and having your engine still run lean.
Check fuel pump voltage / connections.. maybe some problem there??
My vafc is leaner on the lower 1-4K ranges and scales up after vtec. also running 3 bar on the regulator.
plugs are brownish, which means the mix is roughly right.
hmm okay maybe it's time to get a fpr........but i seriously think the mugen chip is whack akuma........
the af curve goes like this!!! i dont have the sheet currently but i can draw it out....

the leaning out is around the 2-3k rpm.......and if im not mistaken thomas told me the optimal during higher rpms would be something like around 13.3-13.5 and the maximum my car could go was 13.7-13.8? (i m not sure abt the figures they might be wrong coz i forgot.....but the difference was definitely 0.x something lar)
Its pretty obvious too coz when driving my friend's h22a manual and b16a manual during the normal cruising speeds they're rpm is much lighter and more responsive than my car.....but when drag mine will win.............
