My experience with forced induction is from WRX's and STI's.

Properly tuned its reasonable to get roughtly 15hp per 1psi over factory boost with supporting upgrades (plumbing, FMIC) tuning and specific high octane fuel in a subaru. So yeah 20psi and 83HP sucks. BUT on 87 octane it is actually quite amazing.
