86 900T 16V running rich.

Hi all. I've had an ongoing problem for about a year now of my 86 900 losing power under boost. To help analyze the problem I stuck it on a Dyno and found that it was running between 13.5 to 11.7 air fuel ratio under full boost conditions. There are no air leaks and compression is O.K. Some items that I have replaced or swapped over to try and locate the problem are: AMM, ECU, 02 sensor, fuel pressure regulator, NTC sensor, injectors, plugs, leads, ignition module, Hall effect sensor. Nothing seems to help and the problem is getting slowly worse! The solution to this problem may be simple but it eludes me. Any suggestion would be appreciated. Thanks.
