Put another way... the ALDA enrichment is limited by the internal full-load rack stop. With the ALDA maxed out (or removed, which I don't recommend for most people), the power is ultimately limited by the full-load fuel delivery (assuming that you have enough air). Spec for 617 boost is 0.75-0.85 bar, or about 10-12psi.

All this talk about boost pressure at a given speed, or feeling a rush of power (or lack thereof), is highly subjective and hard to prove anything with. How about a 0-60 test with a stopwatch, even better if you can confirm the speedo is accurate with a handheld GPS. That's usually a good barometer for your power output.

If you monkey with the full-load setting, you may have to actually lean out the ALDA, as the full load moves the whole rack (as I understand it), and will increase fuel delivery over the whole RPM range. Don't even think about this without a pyrometer. You're safe up to about 1300F, but at 1500F I chicken out and lift my foot. Time for an intercooler....
