Does This Sound Right?


Recommended Posts


my greddy profec b ii ebc reads around -79 (-7.9psi) when the car idles properly

ive read on a couple of topics that it should be a bit more than this. -8.5 or so? do you think this is possibly a vacuum leak or similar?

car is modified r33 rb25det. i am having idle/stalling problems as well, but im hoping its the aac valve since ive already tried most other things. im just not brave enough to try cleaning it, its awfully hard to get at on my aftermarket plenum.

i also suspect my bov may be leaking, is there an easy way to test this? or should i just fork out and get it sorted on the dyno..

thanks for any input
