Expereinced dyno tuner in the area for supercharged cammed ls1 trans am

That’s fine, I’m sure they can both do a great job. Frost has far more experience tuning F/I than either of them combined, obviously that doesn’t mean the other 2 can’t do just as good.

OP, make sure the car has a 2 or 3 bar MAP sensor ready to install. Make sure whoever you have tune it is going to install a 2 or 3bar MAP custom OS. If they don’t tune like that, find another tuner. If not, the frequency limits of the OS max out the MAF around ~500hp and the PE tables will be fudged to make up for it (band-aid).
