That run, 30° total, pulling .5° per psi after 2psi. Normally 34° with the same retard for boost.
Maybe 1/2 a quart. Maybe a little more. I was adding to check the stick from a gallon jug. It didn't slip like most trans slip when low. Maybe the converter didn't fill up? I don't know, but I'll find out next track day if it couple's and works.
