I'd rather not install any other aftermarket parts, as I would like to just remove the module when I need to. I do like the ease of install for the JB dual-cone intake though (something I'm also thinking about).

Also I read with the JB4 stage 2, you can choose from your steering console what stage you would like your car to perform in? Stock boost, stage 1, or 2. Is this true? That's the only reason I'd choose a stage 2 over a stage 1. Thanks guys!

I recently had the chance to drive a friend of a friend's 335 (N55) JB4 Stage 2 (Map 1) and literally emailed Mike at N54tuning as soon as I got out of the car. Install looks simple and seems worth the extra effort.

Good luck.
