    First Tuned

    I’ve been reading and researching between JB4 and BM3. I went with JB4 because they have been out longer and spoke to Kevin, Sr Mod Expert and I don’t want any issues when I bring in my car to the dealership. Also it’s really a preference. Everyone will have different opinion. That said, I can feel the difference already and I’m very happy with the outcome. Of course you have to do the other bolt on mods just not the basic. Like I said is preference on what you are looking to do to your car.
