Hi folks got a question for yall, so I have a 16 STI and I just added a Cobb Accessport to it. On the stock tune I was hitting anywhere between 16 to 19psi on my turbo. But sense I put the Cobb Accessport tune on it ( Stage 1 91octane ) I haven't been able to get it over 10 to 12psi? Now I live in Colorado at about 6000 ft elevation the car is totally stock except for the AP and the limited model upgrades seems like the car is running fine I'm just not getting the boost levels I was getting on my stock tune. So I'm wondering is that normal at my elevation with the different A/F ratio of the AP or could there be something else as the problem? Any and all responses are welcome....Thanks....FC.
