What DTC (code) did he get w/ the CEL?
How long has it been since the air and fuel filters were changed (and what filters were used)?
The fuel pressure regulator spring is a necessity IMO. Do it yourself or get it done. Of course it is always better to have gauges, but almost everyone I know w/ the original spring does not maintain the proper pressure at WOT.
Since he has a 2006, he should have a boost gauge. What is it doing?
You can read up on how to test the FICM voltages if you are interested. A quick search will bring up what you need.
You might also need a new Baro sensor. MAP/BARO/EBP should all read the same at KOEO.
It is possible that the turbo needs cleaning - possibly a new unison ring, but they can't know until they (or you) inspect.
