    I don't think it's your trims, your app is set up wrong (I believe)
    Default wastegate position should be 0
    PID gain should be 20
    Auto shift redux is 60
    FF/ should be 50
    Also, I wouldn't try customizing your fuel bias just yet, let the JB do it. It does a great job at leaning it where it needs to be. Running 10.0:1 is very rich, put your fuel Bias all to 0's and let the car adapt on it's own for now until the rest is sorted.

      Should I have fuel bias at zero and same with duty bias ?

        Duty bias is for EWG, I don't think you have those cables, so it won't matter. 0's for both is a good base until the car is sorted. The only reason you *might want to mess with Fuel Bias is if you run race gas and you have a custom Map6 that supports you leaning it out. Otherwise, you're really not accomplishing much other than creating an additional variable to troubleshoot if something gets weird.

          Always post the CSV for tuning advice. But looks like a setting issue, FUA = 0 for the 2L motors.
