Apologies I made a mistake when writing the post and the post will be corrected. This is at the crank not the wheels.Something seems off with those numbers, even if the tune itself is a good one. Polestar optimized 3.0T cars with supporting mods tend to make about 275hp at the wheels. I have a hard time believing a better tune with all stock hardware would safely make 75whp more than that, or that you’d see whp numbers as high as that on a different dyno. This dyno might need to be recalibrated, or those numbers might, in fact, be at the crank, or with some very generous corrections or calculations anticipating a large % drivetrain loss. I don’t doubt that the tune is a big improvement, but I doubt that other dynos would read as high as this one. 350hp at the crank would be a solid tune and would be far more realistic.
