The skunk Stage 2s are more oriented towards high-revving normally aspirated setups. Duration isn't the only spec you have to look at when picking cams. There's lift, overlap, ramp speeds...

Crower has a well proven turbo-specific cam profile that you can get on either their standard B-series VTEC core which runs around 650 or their "race" core which is another hundred bones on top of that. Regardless of the core, the profile has tons of lift and not too much duration.

Aside from the cams though, the turbo that comes with the Drag kits is a bit large to spool up quickly. Also if you're not doing anything about fuel aside from a MAP sensor check valve and an FMU then your curve is bound to be off.
