I do know that in order for a car already trapping in the 126-128 MPH range to now trap in the 128-130 MPH range - it will take more than. 17 HP. In fact - 25 HP is also likely not enough - and that number is likely in 35-45 HP range. A side by side dyno day would be an interesting experiment to see.

I do know that - if a person is keeping their car stock - it is a significant difference/advantage in the racing world.

For day to day for someone who doesn’t race or had experience with performance cars - they may be hard pressed to feel the difference.

For the price - I do believe it is a solid deal. And if I were getting an F90 with that CE package available - with the suspension, wheels and power bump - I would buy it. Which I did.

I believe I still have the original order guide - I will find it and post it up.

I can provide some real world experience to this point. I just did a track day on Saturday in my 2019 M5C at Lime Rock Park. There was another driver in my run group with a 2018 base M5. During the last two or three laps of our second run session, he was behind me and when we hit the straights I would pull away from him. After the session we caught up and he said he was peddle to the floor and still watched me pull away from him every time. He and I were surprised the 17 HP made that big of a difference.
