I'm running the BTR LS3 centrifugal cam and it runs and drives GREAT. Car is still setup and tuned very conservatively but is a beast. Highly recommend it.

Overlap hurts boosted cars since you're blowing the boost pressure out during the overlap period. The exact same rules apply for boost as for n/a so the power band is the same and low overlap is your friend. The intake duration picks the LSA for you. You don't just say 230 intake duration and the LSA of your choice. Big exhaust duration hurts low end Tq and increases overlap. Advancing a cam changes exhaust events in addition to closing the intake valve and that can hurt you too. Limit overlap to 4 degrees.
