On 100 octane I had it at around 30-31 psi most of the time and drove it several thousand miles, pretty much the whole summer, straight on 100 octane.

In 3rd gear, 20 psi was at ~4100 rpm, 30 psi at about 4700 rpm based on this old log I am looking at. In 4th gear I have logs of 20 psi at 3600-3700 rpm, 30 psi by 4100.

This was my old 4th gear airboy. Note I swapped out a lot of parts and did weight reduction so I didn't know exact weight so I estimated what I thought was high and low weight for the car which is the two lines. Actual power would be somewhere in between.

Edit: In looking back at the log I made that picture from that wasn't even the finished tune. It is about 3.5-4* of timing off.
