What is your vacuum reading at idle ?
Im a bit curious to what vacuum you guys pull at idle... Car idles at about 900rpm+-
according to my apexi gauge im pulling 200mmHG which to me seems a bit low considering some guys pulling 350+..
Vacuum leak maybe ?..All the vacuum hoses seem to be in good condition
Car goes awesome though.. Destroyed a wrx and an audi s5 lastnight

So much variance in vacuum readings with the rotary. IMO. You have big variance based on RPM, idle timing, AFR, and porting... I think the health of the engine is much better gauged with the dyno (specific to your engine). Dyno when you get it... then comparable dynos on the same dyno, across varying time frames.
My street port pulled about 425-450mmhg at ~ 900rpm. Timing was retarded quite a bit at idle....AFR was around 13.5:1
