I gotcha homie, just went through this on the dyno. Took us over 30mins to figure it out.

Take the passenger side spark plug cover off. On the easiest spark plug boot to get to, pull back the shielding a little from the spark plug boot. Clamp the white wire. That should get you an RPM signal.

As far as the boost reference, I have no clue.
