2014 Sonic RS high RPM misfire, I've tried everything
Hello. I recently bought a 2014 Sonic manual transmission. Vehicle came with ZZP exhaust and downpipe, ZZP intercooler and bigger throttle body, ZZP thermostat and a ZZP tune. With this and any tune that I've uploaded that is not factory, it starts a misfire at around 5500 rpm under high boost and full throttle. Under 50% throttle or less, it runs fine. If it starts to misfire and I don't release the throttle, I get the infamous check engine light blinking and traction light. I replaced the valve cover and PCV hose thinking it had a leak, but it didn't fix it. I installed new AC Delco original plugs and NGK iridium plugs, gapped them at .027, .024, .020 and same result. I installed a ZZP coil, no fix. I messed with the tune, changed a lot of parameters, retarded and advanced timing, changed PE, nothing. I also messed with wastegate DC and knock airmass, same thing.If I upload a stock tune from a 2013 Sonic (leaving the transmission settings the same as the ZZP tune since I don't have the stock tune), then it won't misfire. I'm running out of ideas. I'm surprised that the ZZP tune isn't running good since they're a very reputable company. Please help 🙏. I attached tune and a second gear pull log. Thank you
