Dyno Results - 2016 M4 GTS

udm86 · 08-02-2020, 09:39 AM

Just wanted to share some quick dyno results for the crowd!

I added Akrapovic downpipes, BMC drop in filters (removed charcoal filters), and a very conservative Bootmod3 tune (Stage 1 - 93 Octane).

The car sounds incredible and it definitely pulls harder throughout the entire rpm range. Very satisfied!

Do you have stock dyno #s to compare it to?

udm86 · 08-02-2020, 12:00 PM

I do not, sorry.

Can you post the pic of the graph? What was the TQ curve

I imagine with the Akra downpipes the car is insanely loud. The other GTS I've seen video of with the downpipes sounded like a full-blown racecar.

Very nice, video of exhaust? People would love to since there are not too many with Downpipes on these

GTS with downpipes is nice

Nice video thanks for sharing, would you mind posting a picture of the dyno sheet? Thanks

Very nice OP..and promise I'm not trying to flame....but isn't this the same power really any F8X makes with drop in filters, a mild tune and downpipes?

Gomeler · 08-06-2020, 12:02 PM

It's still an S55 at the end of the day.

Here is the horsepower graph. I am going back to the shop for Stage 2 numbers. I will post the torque numbers as well (both Stage 1 and Stage 2).
