ok well i got the pfc controller today.
plugged it in, and checked the sensor sw check at idle, it showed 'bost' (boost) as highlighted, but the rest are fine (engine light stays on all the time)
then i took it for a drive, so other sensors were highlighted, and then i did the airflow/injduty/igntiming/knock check, nothing seemed to be maxing.. airflow rear 1800-2000 or something similar? injduty never reached near 100%, igntiming stayed about 30degrees, but dropped to 20 as it started flashing the engine light, and the knock bar got up to about half way, but thats it.
so now im confused.
