Hey my friend I installed it on my 19 sxl and it's awesome but the bug bite me and now it's all out I did Megan midpipe muffler delete AEM cold air sound plate oil catch can and I just ordered the snow performance water meth stage 2 kit it pulls pretty hard I'm already running vp race gas on map 5 it's greatHello 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!
Make sure you upgrade your spark plugs. There’s a thread on here somewhere. But basically any tune needs to have the race plugs.Any updates on this JP4 tuner? I've just ordered one for an install on my '12 Optima SX that I run 93 octane in always. Just curious how it's working out for others and to determine what map I can get away with on a stock '12 SX. (I'm assuming map 1 for sure and possibly map 2 though I may need to up my octane with Boostane or E85 mix for that.) Just curious. Thanks in advance.
