I've been noticing lately that the horsepower display is showing me different numbers depending on the context that I look at it. When I have the N screen on and floor it, the horsepower peaks up to just below 275, probably around 250 or 260 maybe.

However when I stop the car and check at the log graph it shows the max horsepower to be around 200-230, sometimes lower at 186.

Is there any reason for these discrepancies and should I be concerned? It's hard for my butt dyno to tell but sometimes I do feel like the car is a little slower than I remember, but looking at the gauges such as torque it still seems to be hitting normal power peaks, although the horsepower gauge never hits 275.
