Hesitation, poor gas mileage, and faint "hooting" sound - Help!

These are the symptoms. My 93 900 turbo has hesitation between 2000 and 3000 rpms under medium acceleration and there is an faint audible hooting noise as the hesitation occurs. After that, turbo kicks in strong and the car seems to accelerate fine. I have new plugs, wires, cap, rotor, BPV, air filter, fuel filter, and silicon vaccum lines most everywhere. Overall gas mileage is below 20mpg even on long highway trip. (went VT this weekend - saw lots of classic Saabs). Hestiation is driving me nuts. I adjusted the base boost this weekend and car is faster, but no change to hesitation.
Please help.
Any ideas? What else can I check?
