I agree with everything you said impatient.

I do not have the ability to switch between settings. I can only turn the mbc know up and down. The fuel and timing maps have been tuned for 93 and the a/f was around 11:1, but I have increased the airflow since that tune with a few bolt ons and want to see what the a/f looks like now.

I want to turn the boost up while using race gas. On the dyno with race gas, I would like to turn the boost up until the a/f reaches 13:1, as long as the knock link is cool with it.

The main thing is that I make sure my a/f is ok at my current boost setting (19psi). If the gas doesn't make an impact on the a/f then I will be fine using the purple stuff for the whole session. If the gas does impact a/f then I will be resigned to using 93 pump pee pee and just doing some base line runs, possible adjusting boost for the street.
