I'm pretty sure my Rev 2 Turbo is running lean. I've got it booked in for a dyno session with Interpro next week to hopefully get to the bottom of it, but having read other posts on the subject I'm starting to suspect a problem with the AFM.
So, how do I go about checking that it's operating correctly?
Cheers

Just found the relevant section from the BGB, time to find a multimeter!

Just out of interest what makes you think its running lean?

AFR reads around 17 at idle, get knock at high load and low revs, sometimes get a puff of grey smoke at high revs during wide open throttle.
