MAF Controller for FSI (upgrade Stage1 to Stage2)

Upgrade Stage I Kits to Stage II spec for early-model Mk5 FSI cars. Direct injected vehicles with with ME17 ECUs (i.e. late Mk5 FSI/all Mk6) boosting up to 24psi should choose the standard MAP/MAF-based controller and run it in MAP mode. Those producing over 25psi should choose the High-Boost version.
