As I understand all '85s are low on boost. I wouldn't be suprised if you have 7-9psi like most do. I bet the fueling in the IP is low on them too. 11-12psi seems to be the factory spec for the 617.
I picked mine up from ebay for $12 shipped. Just install it between the wastegate and compressor housing. 30min job. Just be sure to have a boost gauge handy to measure it for proper spec.
