guys i have a 2004 996TT with the following setup:

1)Modified ECU by gemballa 570HP
2)exhaust system with headers by Gemballa.
3)Racing clutch with flywheel.
4)GT2 sports intercoolers.
5)K24/K26 Racing Turbo's By FVD.
6)BMC sport air filter.
7)FVD Diverter Valves.
8)FVD Fuel pressure regulator.

The car feels and drives strong, my question is there anything wrong with this setup since it has mods. parts from two different companies (FVD, Gemballa)
The only part left i need to install is the FVD Air Intake Plenum.

Your advice will be most appreciated.
