For anyone that might still be viewing this thread..... I finally went with.the JB4. The difference is like night and day. JB4 on map 2 and 3 transformed my 2.0 into a beast! Could be the mods but for what ever reason, I would have a hard time trying to tell someone that this is a 2.0 4 cylinder car. Check out my recent posts on other threads. JB4 all the way.
