I would like to get some datalogs to look at, if anyone in my locale has the program, let me know. But I did find a local shop that has a dyno and hope to get a couple of pulls off before winter hits and the car gets put away.
Not sure if the OC is a new product but it's a prerequisite for the S3. A piggyback version if your car already has one, or a full size version if your 335i didn't come with one. The latter adds $1000 to the cost I think.
