What are the levels / stages of tune on say a 240ps WRX Scoob?

Depends what year / model, at that power would be close to, if not standard.

Depending on what you want to spend i would do (am in the middle of doing)the following:

Exhaust with de-cat
FMIC/STI 8 TMIC
440cc injectors
Apexi ECU
Panel filter if running TMIC, Ind kit if running FMIC
Possibly headers aswell

Fit 4 pot brakes before doing any of the above

the headers are worth it for the sound alone.
