I’ve installed the JB4 Tuner, a Borla exhaust and the Ultimate down pipe/ mid pipe to my 2019 KIA STINGER GT2 RWD. I run on map 1 (91 octane), map 2 (93 octane). This is the 3rd time EL comes on, car Boggs down. Blown plug. I have to disengage the tuner and use car as stock. I need help in rectifying this problem. Does my car need to be dyno tuned or can someone help me with map 6 (custom setting)? I’ve contacted a racing garage(in person), but they have yet to call me to say they can help.

What do you mean by blown plug? Also what plugs are you using and what Gap?

Please upload a map 1 log when you get the chance. Thanks!

Denso high performance plugs gapped at .022. I’m assuming it’s a plug because of the last two times. As soon as I get on the peddle, it’ll buck and bogg down and my engine light comes on. I’m being told there is too much air coming in and the computer doesn’t recognize it so it forces extra gas. I’m not to familiar about this stuff.

Read the fault codes in the app and post up a JB4 log.
