I've never run a piggyback on my '20. Since posting my last reply on this thread I grabbed a Dragy and on another thread posted a 3.33s 0-60 time with BM3 Stage 1, no trans tune, on winter tires. I've seen times as low as 3.1 running a JB4. Maybe I could match that under optimal conditions but for me it seems that the 0-60 performance of both tunes is similar.

I'd be interested to know if anybody has ever posted dyno numbers for the BM3 Stage 1 tune on a '20 or later 550. My butt dyno confirmed a significant boost with the tune, but I don't know any actual numbers.

I've requested dyno graphs from bm3 many times and from other Tuners using bm3 and have yet to get one. If there's one from a Stage 1 93, I would be very curious to see.

By my calculations if the various baseline figures of 480hp and 550ft-lb at the wheels then stage 1 should net 590HP and 616Lb-ft at the wheels. That seems reasonable for a conservative OTS tune. What is unclear is how big a difference catless DPs make, but the M5 forums says the factory DPs are pretty good so you won't be making much less with them vs. catless. i think going to E30/E50 will get you a lot more than a custom 93 tune and catless DPs. Hassle is running E anything all the time. |

These questions would be easily answered with a few dyno runs. |

I suspect I'll get bored quickly so I could do a baseline, OTS stage 1 and then custom on the dyno. Not sure when I will be doing that, but might be later in the year. I'm hoping some xHP tweaks and stage 1 OTS I can do a 10.8 1/4. We shall see late September. |

It's also discomforting that they have never published an update to the original N63T3 tune, released 2-1/2 years ago. I feel like it's an afterthought to them.

I have a m850 but I put in RVG however... they didn't ijitially fit (despite being assured they would) so my shop had to do a lot of work to get them to fit. If you have a finicky shop they'll just tell you sorry, they don't fit. I wouldn't recommend RVG.
