Stages can be kind of confusing.
For example (minimal requirements):
Cobb Stage 2:
Cobb Accessport Access ECU
Vishnu Stage 2:
Vishnu Reprogrammed ECU
Standard Series 3” Cat-Back Exhaust
Standard Series 3-inch Down-Pipe with High-Flow Catalyst
STi 550cc Injectors
High Flow Fuel Pump
Flex Uppipe Kit
Power Pulley Kit
TurboXS Stage 2:
So, in the end, it really depends on the manufacturer. Let's just say with your setup, most people will label you as Stage 2.
