as the title surgests do i still nead a fuel cut defencer even tho im goin to use the power fc surely the power fc has its own inbuilt fcd does anyone no?
thanks gav
you don't require a FCD with Power FC, as the max boost / sensor output will be limited by the measuring range of the MAP sensor used.
Typically the OEM rev1 / rev2 MAP sensor will allow up to 1 bar boost.
The OEM rev3 MAP sensor will allow up to 1.6 bar boost. or,
you can configure the Power FC to run with an aftermarket GM type MAP sensor that will allow maximum 2 bar boost etc
