Stage 1 is how the car should have come from the factory. Got the Accessport Today and couldn't wait till tomorrow, so I flashed stage 1 on the 04 WRX. Wow, smooth linear power, quicker boost response. Very happy, not even hitting target boost yet.
Tomorrow, Downpipe install and Stage 2 flash
Should be a fun weekend, may take the car to the Test and Tune and see what the 1/4 mile is.
