    Analysis of my log - C63 AMG

    Can anyone support me in analyzing my log file? After several modifications, this is the best performance I've managed to achieve with my car. I've read that the torque values provided by the log may not be very accurate, but they seem good to me. Can anyone provide feedback on it?

    Your MAP is low, so you're at altitude? 3500'?
    Fuel trims are very negative. Not sure how you managed that but maybe bigger injectors?
    Otherwise is looks ok to me. Should post the stock and modded tunes too, and imo collect more data, like Injector pulse width, fuel psi, ping retard.
    Doesn't hurt to add cam position desired and actual to be sure it's doing what it's supposed to.
    Here's all the stuff I watch. Of course ignore the turbo stuff:
