2013 Genesis coupe 2.0t... only mods are a turboxs bov and a btr stage 1 tune. Car has been great about 80k miles. Always change synthetic Mobil 1 every 3k miles have never missed a single oil change. Was driving hard yesterday and took a pull almost to redline in 3rd. All of the sudden approaching redline there was a pop or backfire as loud as a gunshot and then it ran like crap. Shut her down and got her towed home. She still cranks fine (no grenaded metallic rattles) and even starts but just runs like a**. We are thinking skipped timing but I thought the bk2s had a stronger chain...? About to do a compression test and I'll post the results. Any input, advice, etc is welcomed and I will be checking posts and posting updates frequently. Let's get her fixed!!
