With the past 2 months I've installed the HPS short ram intake, Tanabe Medallion axelback, and the agency power crank pulley. All of them were installed at a shop. I'm wondering if the cars ECU will automatically adjust itself or if a manual reset is required. I definitely feel the car being more responsive but from what I read from other users about the gains it seems I'm lacking something. I know that the car wasn't manually reset after my crank pulley install but it might have been for the intake and exhaust.

 

Modifications that minor are well within the tolerance of the stock ECU, and it will adjust over time (don't expect additional performance from where you are now).
