well i searched and i found a few things to make me think that something has to be wrong with my motor. here is the setup:
stock b17
greddy td05h 18g turbo
greddy manifold
b&m fpr
hondata
2.25in piping
2.5in exhaust to a magnaflow muffler
in the hondata will datalogging i am registering 30-32in Hg vacuum while idling. i will hook up a gauge to see if the reading is consistent. any ideas on why my it is so high? n/a the motor idled at around 19.5-21in Hg. any feedback would be helpful.
