BMW M850i Stage 2 E30 tune with VRSF downpipes.

Testing new revised tune. Now working properly. With 1ft roll out like manufactures and Car mags advertise it was a 2.96 on this run spinning off the start. Need the right road for a 10.6 run and better air conditions and a track for 10.5999😁

How are the vrsf downpipes in terms of sound and performance. I have a 2021 x5 m50i straight piped and no tune yet but waiting for a Carbahn tune for the 2021 variant. BMW spokesperson told me that the tune will be out in another 4 or 5 months as of yesterday. Do you still get a ton of burbles? That’s something I definitely want. How is the smell? I heard some people say keeping the secondary cats will remove the smell of the catless dp but I don’t know if that’s entirely true. I really like the sound of your car so any info would be great.

The vrsf catless downpipes it's fine. Yes there's a little bit of a smell but only outside

[@DRAXXASM850i]

Sorry wasn't done. The burbles are in the tune. Mine are there but not aggressive. It's something I could change easily with the bm3 app. That's what was used for a platform.

[@Ishan_raj06]

Is it possible you could make a video showing bm3 tune with max duration burbles and max aggression burbles?

[@DRAXXASM850i]

@@Ishan_raj06 Guessing you could find that on you tube but honestly I never get into the app and mess with settings. The tuner has everything set to my liking. I'll do a search myself later today and see if I can find something for you for comparrison.

Do u believe a 2016 750i xdrive can pull off similar numbers considering it’s almost the same weight ?

[@ericp758]

Engines are too different

@@ericp758 aren’t they both n63tu?

@@shelbyhaiketic4212 Well, yes but a 2016’s 750i has got the N63TU2 (444bhp) and the M850i got the updated N63TU3 (523bhp). Just search them up and you’ll find the differences.

[@Youtuber-st7wo]

Proabably not, aerodynamics of the 8 series is better than the 7. Also the 7 has a N74B66 with 445 Hp, and The 850 has a N63 with 523 Hp.
