Hello everyone, I've noticed many forums and videos on the Kia stinger with burger Motorsports jb4 destroying the streets. But us optima owners haven't gotten much love unless it's talking about lap3 tunes. Ive had jb4 on other cars and loved it but not on the optima. I guess I will be one first to have jb4 on a optima since no one has talked about it. Can't wait to see the results!
