(1) are you sure your timing and vacuum advance/retard are ok? If the retard under boost wasn't working properly, would that cause pinging and force the APC to dump boost? I assume you have checked this with a vacuum pump on the distributor capsule...
(2) fuel pressure--- it's pretty easy to put an electronic fuel pressure gauge on the end of the fuel rail (closest to firewall), I think autometer has one for $100 or so. You can tap into the banjo bolt on the rail end. Then at least you would know what the pressures were under load, etc.
