Could be a ton of things man, try to provide more info. Does this happen all the time? And what happens when sputters? Do you have a decent tune on the car? If so, what A/F ratios are you seeing during these periods?

Even though you have a MAF-T in blow-through, you could still have a ton of leaks (trust me, I know from experience):
-TB Elbow
-TB to Manifold
-Manifold to Head
-Any of the injector seals
-Any of the vacuum lines coming off of the intake manifold.

Do a boost leak test & then do it again. Once you've completely eliminated it from the equation, just do it again, trust me.
