It's barely adequate for the stock 10 psi. At the least, I would pick up a used Pettit or PFS SMIC, as they can be picked up at reasonable prices and don't require a Greddy elbow or battery relocation.
I know a lot of people run over 10 psi on the stock IC but they have very high intake air temps too. Also the pressure drop of the stock IC means your turbos are working harder to produce the same boost. When I installed my used PFS SMIC (which is not a state-of-the-art SMIC, but it's pretty good), my boost jumped up about 2 psi in the high rpm range.

I might be going up to a large from my PFS medium next week. rynberg has it right. Get a bigger IC before you turn up the boost & run race gas if you are going to push your luck.

my car made 360whp and 310wtq with the unlimited ECU. i have a 3inch DP and 4inch MP and EX, greddy smic, pullies, profec B , fuel pump. i also had colder plugs and an MSD 6A.
i ran 14 psi and used C16.
by the way, i had the stock twins and motor with about 36K miles when i did the dyno pulls.
