I haven’t really played with the flash options, but do you think it was heatsoak on the previous logs? Or are there no signs of it?

No. IATs at less than 100F, and heat soak isnt going to do that. There's very clearly a torque limit issue when the boost target is low

Hello, i own 440X Drive, i have the same exact issue, every time i floor it power is ok. but after 5.5k rpm there is power leak. Did you fix it? If you did, please reply, i'm looking for solution

It kinda just went away, I switched gas stations and made sure the octane and ethanol content is correct. I haven’t had that problem since. One time I anti-lagged tho and the car cut power. My “solution” was good fuel and no anti lag😂
