jb4 reviews

Hey guys, I have called a few tuner shops that all say they would stay away from the JB4 due to too many issues. However, on youtube etc the reviewers usually say that it does ok. What has been your experiences with the JB4 (if installed of course)?

Not sure why they would say that. I've never had issues with the JB4 on my car. It a alternate solution that keeps you from having to hack into the ECU. It's possible they want to sell you a custom tune for more money.

Same here. I’ve had it on for 30k miles. No issues and great customer service
