One flat may do the trick. Middle of the sight glass has always been best for me. It looks like the PJ comes in at 3400 by your readings.

Hmm….I was thinking that at 3400 the secondary was might be starting to open. The stance of the car give this thing the aerodynamics of a brick at those speeds. I could be wrong. I’ll have to look at that next time out.
