I thought that was odd as well. I received my JB4 today. Installing tomorrow.

Please report back how it's going, there's so little info out there right now. Mine is also scheduled to arrive tomorrow although I still need to get the first service done before I put it on.

This and undoubtedly similar tuning exercises in the future tell a compelling story about S58 engine and its potential.

Yeah but for how long? With the non-comp models apparently having the power limited due to the manual gear box, we don't really know how much power the other components like the X-Drive will hold.
I mean who knows really? At 670 whp and AWD, you could hit low 10s easily.

Once again.. FBO, OTS tune, E85 or race fuel and a good driver this platform will run high 9's IMO but low 10's for sure.

This is now the third gen BMW w/ the JB4 and even though the numbers get higher its always the same sequence of reactions. Funny to see that.
