I'm getting my PFC tuned to run @14psi on pump gas. I'd like to be able to put in 100 octane and turn up the boost when at the track or for fun occasionally. I know I can't use a map tuned for race gas with pump gas, but is the reverse ok?

I know it won't be optimal since with the race gas it could run leaner safely and the timing could be advanced.

 

I think the bigger issue is that you get it tuned for the maximum boost you want to run. I think it should be fine to run your car on race gas when it was tuned for pump gas (though I could be wrong, so please post if you know otherwise). Here is my impression of the tuning issue:

Tuned on pump gas & 14 psi
race gas & 14 psi: no problem
race gas & 17 psi: boom!
