Is tuning a Subaru WRX STI possible?
I've been reading a lot lately about performance tuning, and I was wondering if I could tune my Subaru WRX similarly. Is tuning a Subaru WRX STI possible?

It is 100% possible to tune a
Subaru WRX STI
—in fact, there are several ways to do so. For simplicity’s sake, however, we’ll divide them into two overarching categories: electronic and mechanical.Electronically tuning your Subaru WRX STI allows you to install performance upgrades without changing the car’s physical characteristics. This is accomplished by remapping the engine’s programming using an OBD-II scanner or the engine control unit (ECU); using this technique, the driver can alter power output, fuel efficiency, etc.
Mechanical tuning, on the other hand, does alter the body/physical appearance of your Subaru WRX STI through the installation, replacement, or modification of performance enhancing parts. An upgraded air intake—which helps increase horsepower and fuel economy—is one of the most popular tuning modifications made to the Subaru WRX STI.
