Im sorry but those wheel to crank conversion are way off. Adding an additional 26+% from wheel to crank? That is crazy talk. 18% is a more realistic number.

Oh and another thing, there are Other F10 535i JB4 stage 2 dyno
out there than the one you shown.
Like this one, much smoother:
Map 2 (14.5psi)- 297.98 whp (375hp crank aprox). 365.95 wtq (446tq crank aprox).
Map 1 (12.5psi)- 298.97 whp (372hp crank aprox). 347.91 wtq (424tq crank aprox).
(*Note, this guy have downpipe and exhaust. +75HP and +146lb torque over stock ... this is obviously a guy trying to shoot for most HP lol)
So if we go with that, he has gained 50hp over stock, that is with tune, exhaust and downpipe and 95+ octane (downpipes usually add 15-20hp).
I for one am not anti BMS if that is what you are thinking. If you check out my previous cars I have had their tunes all the way back when JB2 was the newest and hottest thing on the block, then went to the JB+ when it was in beta and then jumped up to a JB3 and had now tried this one my F10. I am just being realistic and stating you have made at most 40hp gain with your exhaust.
Also dyno's without a baseline are basically worthless as far as showing how much HP one has gained.
Just for the hell of it.. Here is my thread I started when I installed mine.. Click me... Do it now! What are you waiting for!!!
