Sounds about right. You really should email Terry directly. Again... with the m35i pushing 22.8psi out of the box it is really high. I think on the X1/X2 with the "normal" b48 they are somewhere around 16psi I believe someone told me one time. With the engineering totally being able to handle 4psi over, this is why it wakes up these cars and bring their 228hp closer to 300. If you think about the similar engine already at 22.8psi (and even better with lower compression to push that high) We are already sitting at way higher boost. This is also why we're already at 300hp. We're most likely well past that sweet spot of exponential power vs boost additive.
