cobb does not make a map for 2003 wrx's with AEM intakes. it would either need to be stock or cobb. see the link above to view the maps available & map notes which will tell you exactly whats needed to run them correctly

2003s are more forgiving when it comes to tuning, which is a good thing at least.

If you don't have access to put the stock airbox back on, then I'd run the Cobb Stg 2 +SF Intake map.
