You don't want a narrow LSA if you're boosted or you'll leak out your boost pressure. Would make a nasty exhaust note, though!
I was curious how that cam compared to the stock cam and I found these specs from GMPP:
Part #12561721
- Lift: .467" Int./ .479" Exh.
- Duration:201° Int / 196° Exh. @ .050'' Lift
So, your cam has a little more lift and duration (as expected), but the LSA is stock-like. This will let more boost pressure in but not bleed it out through the exhaust. It should sound meaty and the torque curve should complement that of the supercharger's.
