Don't know if this is true or not but I thought I read somewhere here that the S2 pcm will only work with the S2 Siemens injectors. Has anybody with S2 tried switching them yet to see?
Also, Nick can you explain what the turbo restriction is if you use a smaller intake with an adapter? I was going to use my AEM but use a 3" to 2.5" silicone coupler for the turbo.
