Right, But if I recall its not really worth it unless you want to spend $600 to be able to clear codes and have a valet/anti theft map. From what I can see Cobb does not offer "staged" maps for the NA subys. But if you can Protune with AccessPort on the NA subys and were doing something like this..... I could see the need. but at that point one would go with what the chosen tuner works best in be it Accessport or OpenSource.
From my experience with the NA suby ECU, my friend had a 2000 2.5rs coupe. We put an intake, headers, CBE, reset the ecu and it ran like a champ. It never have him any trouble. However turbo subys are another story, exuding 02-03 WRX, if you put a downpipe on the car and do not reflash its not going to run right. For any cold air you should technically get a tune or the motor will have lots of hesitation.
