interesting.
I have a FQ. not used yet it arrived today..w a 110v/14v DC adapter.
but was planning to only do vacuum testing anyway. but thank you for reminding me that i should assure calibration before jumping in both feet.
i'm very much interested in exhaust flow as on an A series head there is lots of work there to be done and on the latest cams and small engines the exhaust manifold type affects power by quite a lot (>10%) .
i'm planning on flowing both intake and exhaust both directions as well (but pulling only).
