First, welcome to IGOTASTI!!! You're going to absolutely love it here!! Post some pictures of the ride!!
Second, did you purposefully purchase an AEM intake for your car or did it come already installed on the car?
Third, are there any other modifications done to the car? If so, please list them all.
Fourth, you stated that you have "Access tuner." What are you referring to exactly? Do you have a Cobb AP?
Fifth, there may be an OTS map for the Cobb AP for VA STi's. I'll have to look to double check, but please answer the above questions before we move on.
