weiand 6-71 blower questions

Hello everyone, iam new here and hope someone can help me out.
I just recently got an 82 camaro with a 30 over 350, afr heads, 6-71 blower and dual holley 600's. The rear is a moser 9" with 456's and is a mini spool. I need all the help i can get on blower engines as i have never had one before.
I don't really have any specs as what the c/r is, or cam specs, what boost its pushing etc.
Iam looking for info on how to figure out what boost iam putting out, or ways to change the boost for more power. The only thing the previous owner told me was it was running 13% underdriven, and is detuned for cruising on the streets, which is meaningless to me as i have no clue what it means.
My major problem right now is, i just don't think the engine is performing at low rpm like it should be, especially with the 456 gear ratio. Iam not getting much power until over 3000 rpm.
Sorry this post is so vage, but iam looking for a tutor in blower engines, as iam new to them.
Thanks in advance for any help anyone can shed onto me.
Daryl
