3S GTE boost control

Have a mostly OEM 3S GTE Gen3 in my Celica ST205 have replaced the OEM boost control with a 3-Port MAC. I have my Boost target set to 215kpa, but when I get to about 205-210kpa, its hitting an ignition cut somewhere and backfiring/dropping revs. I have looked around and can't figure out what's causing the cut. Protection is set to 216kpa.

Your MAP Limit Limit Control Range is set to 5kPa so it will start cutting at 211kPa and you are hitting this limit. You are also hitting your RPM Limit twice in that log.

Also as a side note your Lambda value doesn't follow the target very well in the ECU.
