Getting on hwy throttle response sputtered followed by rear axle, stabilitrac ,traction control and engine light blinking. When stopped push pedal car coasts for 15 sec than turbo kicks in and goes . Every stop on way home same thing . Next morning fine until getting on it and again it happens . Once in sport mode and one in tour mode. Have Trifecta tune don’t know if that is issue have for two years and no issues.
