2004 Subaru WRX – AMR Performance Reviews
- Upg. Turbo Back Exhaust
- Upg. Intake System
- AMR Performance (www.amrperformance.com) custom tuning
Brandon’s vehicle was in bad shape. Complaining the car has no power over 5000rpm and horrible idle, though, under full throttle, the turbo would scream and you would “think” it was flying. After doing some base pulls we are able to see clearly that vehicle is NOT running optimal.
Our engineers went right to work, tuning the vehicle’s factory ECU and making severe improvements running ONLY 16.5psi. Gains can be seen clear on the power plot posted above.
