So I just recently got into turbo Subarus and cars in general. I have a 2008 legacy gt completely stock with an auto and was think of getting an access port. I don’t have access to a tuner and was wondering if it is better to keep stock tune or stage 1 93 ots map. I’m not looking to further modify the car I just want a reliability but I feel the stock tune is just pretty dull.
