s14 sr rev limits early 5000rpm wtf ?

[alesserfate]

anyway back to this again, motor is running again, last night i sucessfully adjusted all the settings and it was idling properly and pulling hard steady at 11.0AFR at 12psi all the way to redline

however after increasing boost to 15psi and compensating fuel for it, it would start to rev limit at 5000-6000rpm again

i've checked that its not running too rich or too lean, i've also checked the ignition timing multiple times and cranked and its still what it was before, 7 degrees instead of 15 (just to be safe)

at the end of the day i turned the boost back down to 12psi and i can't get it to stop rev limiting there

also thought about decreasing BKR7E spark plug gap from 0.028 to 0.026

if anyone has any ideas why an ecu would rev limit early (besides too rich/too lean) please post up

thanks in advance!
