Additionally, look for any fuel leaks at the clear plastic fuel lines and on top of the IP at the delivery valves. Is possible that under higher fuel demand it is sucking some air. The pre-filter oring would be the usual culprit in that event.

The MAF fault on the 606 turbo is usually pretty obvious in my expirience. Should activate the CEL, there is no turbo boost and it is difficult to pull more than 3k RPM's in any gear.

*edit* If as Matt suggested you are not developing boost, the transducer at the EGR is the same as is used at the turbo. The two can be swapped to see if that is the problem.
