This is another 02 WRX with a basic VF34 setup:

VF34
STI Pink injectors
Walbro
USDM STI TMIC
Perrin catless DP
Apex Catback
Hallman MBC

Keep in mind this is an 02 WRX with 80k miles on it and the customer requested a fairly conservative tune. At sea level this sort of setup normally makes about 270whp and 240-250ft-lbs. So while its evident that the elevation hurts top end flow a bit, this car again shows that its possible to extract significantly more mid range torque than at sea level with the same octane fuel.

Here's the road dyno plot on 91 Octane:

The car felt surprisingly torquey for a 2.0 and I almost never see a 2.0 with VF series turbo make more torque than horsepower on 91 Octane. I kept asking the customer if he had headers but we confirmed that the headers were indeed stock.
