JB4? Questions!
You guys with JB4, please chyme in.
A few questions that I would really appreciate to have answered. 1) How has your experience been with JB4? 2) What would be the advantage/disadvantage of JB4, as opposed to JB4 stage 1 tune? 3) How are your dealerships reacting to your cars having JB4? Many thanks! Pat
