Default Pardon my ignorance, but what is hp/ft?

HP is power, lb-ft is work...what is hp/ft?

prob 160-165 hp and 170ish tq (25% dt loss is for hp, torque is way harder to calculate)

Maybe you should post the dyno plot to help with the discussion?

Not without a baseline it is impossible.

Default These are APR's crank numbers for the Stage 1 V2 chip...

so I'm wondering what the numbers at the wheel are, that is, what I should have been.

Default Given "the other car" has heavier wheels than you do, I think the 22% loss is a decent estimate...

Still think it may be worthwhile to post your dyno plot, to see if people here has any suggestion, other than "software problem", why your numbers are how they are.
