I'd like to tell you that you wont notice a difference between 10:1 and 12.5:1 but id be lieing if I did. Might be able to do something with timing to achieve close to the same power and response but i dont know that for sure.....easiest thing is to increase boost, but being that your super charged that might not work depending what pulley you have now.
Best I could tell you is to call around and see who is offering 12.5:1 4032 pistons, and if your search fails then call some shops like full blown or element tuning who have built these engines for boost and find out what they suggest you do.
Edit: Full blown and element tuning were just shops off the top of my head that have had success with boosting this engine, thats not to say there aren't other shops you can call.

I'll do some calling around. Hopefully this won't be a big PITA.

Why such a long wait to find out what happened?

With a 70mm pulley I should be around 11.5psi.
The wait is because the mechanic I trust to do what I can't is out of the country.
