I haven't seen anyone recommend POS, Spark plugs and Coil check. This is the 
first place to look.

A failing POS could exhibit these type of issues. If you are loosing power 
under full throttle (compared to 90%) this is indicative of spark plugs and or a 
coil starting to fail.

27 PSI is a lot of boost ... if you don't have this area working perfectly 
the car will have constant issues.
