I know an extra 100Hp is pretty silly but I was wondering if someone can tell me why such a difference. 2016 M6 P1X. I have been using engine brake torque and a math for horsepower. I'm fine with the engine brake torque calculation maybe not being overly accurate but I would hope it would show directional differences. Two runs one at 14 and other at 16ish up top. Only other obvious difference I see are the cams are in different locations. 14 degree one stayed in optimum power for the most part. What I am unsure about is about a 1/3 of the way through the second run it jumped out of vct optimum power and was in best fuel economy. Only difference between the two tunes was adding a little more timing. I've attached the logs and current tune file. Any thoughts or insights to help a noob out would be appreciated
