Purely an educated guess from a 27 year history of modding VW's.
Admittedly much less modifying in recent years as I bought newer cars and wanted to preserve warranties.
BUT I'd hazard a guess that an ECU remapped car would produce identical figure with or without PP.
However a tuning box goes downstream and amplifies the boost etc post ECU so my theory is the PP would produce a 10bhp better figure...
