Do you have any kind of piggy back or engien management in your car? If you don't I don't believe there is anything out there to tune a Stock ECU yet.

IF you don't there is nothing you can do except drive the car around hard for a short time after a ECU reset. This will cause the ECU to notice difference in air flow and adjust for it. That is about all you can do.

With the ECU reset, is alot of power lost for a period of time? or will it go back to stock and "Learn" that theres more airflow and run better that way? I dont know much about car computers as you can see. haha

No problem...

The ECU reset will set go back to the base map for the WRX. Which is a good starting point for the WRX. From there, since you added the intake, the car will readjust differently to that mod. It will notice more airflow and therefore either need to add more fuel (more then likely) or pull timing (doubtful).

The other suggestion is to put everything on and don't do an ECU reset, because it will notice more airflow and start adjusting anyway. So either way will work.

I am not sure if you will notice a big difference or not but you might with the intake. The hoodscoop I would doubt you will notice anything from that. Could be wrong though.
