cuts out at 5k RPM??? why?

!!!!!FIXED!!! (but read anyway)
like the title says when i get into boost it will cut around 5k RPM the boost cut options are set way over what im boosting, revlimiter is set over also ...what could cause this... it never did it when i was NA i could rev to whatever...the plugs are gapped at .027 any ideas ....its really annoying also im using 550cc RC injectors are stock fuel pressure...according to the tables it says there maxxed at like 11psi??
!!Problem cause!!
the problem with this was the injectors were really maxxed out according to the map...My wideband was reading a normal airfuel ratio in hondata and on the guage.. but i decreased fuel a bit and it stopped but was sluggish ....then i finally got it leaned out right....and its running good..
i disconnected the wideband from hondata and the guage reads totally different, but when i plug it back into hondata the guage changes (goes leaner) the AFR was reading right both ways at idle but was WAY off in the higher RPM...cause i did have to adjust the voltage scaler a bit to get the 2 readings (from guage and hondata) the same at idle. whats causing this i really wanna tune this thing...it feels great on 6psi..
im using a PLX M-250 with guage and having the signal coming in thru the ELD.. using a PR4 ECU. PLX M series is selected in the wideband settings menu.. please help...
