is there two part to accessport that you have to buy because i saw the accessport and then a street tuner version or do i have to get both of them?
No, the Street Tuner simply allows the user to create their own maps for the AccessPort. For most people, the Cobb maps are just fine. If you are going to run a larger turbo, then the Street Tuner will allow you to account for larger injectors and allow you to tune for the new turbo. If you have no experience tuning a car, I would suggest just getting a ProTune from an authorized pro-tuner. Jorge makes regular trips to the MSP area, and he does a really good job of giving safe tunes.
