"On the N63 platform a huge hold up in performance is the lack of twin bank wastegate control on the JB4. At higher boost levels the banks go out of sync, and there is no mechanism to bring them back in sync. We may develop another N63 board to accommodate this issue if there is sufficient demand. But, it seems to be the N63 is fast approaching a dead platform."

Is that what you were referring to regarding the N63 platform?

For more power JB4 for reliability Tune, but keep in mind eventually stacking both will be possible just not yet.

i think solution for the MAF issue would be to flash the DME to ignore that there is no MAF just like the down pipe check engine.

The reason the F10 550 is not so tuner freindly is because bmw wanted it that way so BMW could sell M5's. If you want a faster car buy something lighter that has more power potential. I could of had and modded an '11 zr1 for the price I paid for my 550 and It would smoke any and all modded 550s, period. This is just a waste of time on this fat pig..

Think it is pretty tuner friendly to reach just over 500 whp if you ask me.... To each their own. However, I have a family and need a 4 door car that is comfortable to drive but can still go when needed, affordable, and can take an extended warranty on for peace of mind. 500 whp is also plenty. I am not going to drag someone every single day going to work but fun to open her up when you find yourself on a clear straight road...

Last time I checked there is nobody tuning any N63's that have been proven with dyno numbers, dinan has been proven to be bullshit and the jb4 is Not a tune. If you know any proven tuners please do tell, but you dont and this car is not tuner friendly or there would be plenty of tuners out there offering options. Lets not bs here, these guys want it to be as fast as possible or hit 10's and its not happening with a piggy back on an n63 car. Also 500whp is nothing these days..lol

Hilly · 11-18-2017, 09:04 PM

pointless argument..Don't you own a 550i? Sell yours if you not happy with the performance. Again, to each their own like I previously mentioned. 500 whp is plenty for me. Sure there are guys here that want more, don't see a problem with it....rather nice to see how far a platform can be pushed (if any)

You would never win this argument since you missed the point of my first statement. let us all know when you get 500whp.

500whp has already been achieved by Terry at BMS.

Where can I get that firmware and map? Anything else needed? I currently have the S63TU Jb4 with BCM module, n63intakes and down pipes coming.
