Recent tune on a MY09 WRX. Vehicle already had a prior tune and we were commissioned to fine tune it.


We also took the opportunity to do a before and after run on this vehicle as the owner supplied an AEM CAI.

Initial Power Run with stock air box vs CAI on MY09 WRX:


The result was 262Hp and 371Nm @1.1 bar. Would have loved to go 1.3 bar and more timing for a smoother and higher power and torque curve, but we kept it at 1.1 bar as we were commissioned for a fine tune to improve on the power and torque on low boost.
