I am sorry, relatively new to te forum and not sure if I'm in the right place. Bought a JB4 stage 3 module about 2 months ago and have since sold my 135i for something a little faster But it was only in my car for 2 weeks and made an amazing amount of power. It's the jb4 only and is for sell for 425, and i will ship it in the US. Feel free to contact me with questions;
