This tune feels so much faster but I'm having issues with misfires. Swapped plugs and coils to Delphi coils and Bosch copper spark plugs. The car still got a misfire above 6k rpm but instead of being cylinders 4,5, and 6, it's only misfiring in 6th now. Hiccups on cold start are gone but it now hiccups on idle. Injector and upgraded pcv we're my next course of action unless you have advice. I also got a 2AAE Dme: Fuel pump code, and 2C7C - O2 sensor after cat:signal.
