Subaru WRX ECU Shootout 

"Power without compromise, that's what we like to see".  

Fast Fours and Rotaries Magazine  


"This ECU "shootout" was initiated in response to the huge interest in after market ECUs and what they can do to make the WRX even more of a beast than it already is.  What started out as a two month project evolved into a six month epic with countless hours spent researching and just under 8000km of road testing."
