Can anyone provide a link for a genuine walbro 255 that wil fit in a 99 9-3? Also are the green giants going to flow enough for stage 5 with a 19t? Im also assumming that GS is one of the only places to pick up a 3 bar map sensor? maybe someone can shed some light but 85 seems pretty reasonable for it anyways. Im looking to get these parts within the next couple weeks so i can head over to Mike D's and get a full stage 5 road tune while on break from college.
