i have some graphs ill dig up. the pt88 was slow to spool on my 365cu. a 76gts would of been just as fast if not faster.
my s91 400cu spools at 3500, full boost by 4500. entirely different animal. power goes up and never falls to 7200rpm.
here is a video of the spool
this was a z06 making 760-780rwhp. he got the first move and is supercharged. your tune can help a little with spool also.
additionally i was 12psi of boost.
personally the pt88 is a poor turbo for out ls1. personally id would do a 76gts, it will make 750rwhp. if you want to go higher than that, get a T6 80mm, on these trucks you would never need anything bigger unless you want to put 1100+ hp to the ground.

Is that boost creep in the vidoe or are you pattin the gas??

Yeah you might as well be hauling around a pallet of bricks with those times 
It would be interesting to see what a T6 version of your turbo would do to your track times, though. A dyno graph would tell the story a little better, but I hear you're not much of a dyno guy
