Garage List
2018 BMW M3  [0.00]

Booymod3 Stage 1 Dyno

Before and after, 1 week apart on the same dyno.

Baseline: 2018 M3 Competition completely stock 25k miles
Vs.
AR Design catless and resonated DPs+ K&N drop ins + Bootmod3 93 Octane Stage 1 OTS tune.

HP gains seem light, especially considering I added catless DPs. Maybe the car needs more miles on it to adjust after all of the mods? 20% torque reduction in 1st and 2nd but I can’t imagine that impacts a run in 5th.

The downpipes do not add much power, especially when you are using map 1 and not map 2.

you made a 16% power increase, the advertised power increase is 23%

running map 2 allows 3% more power (~12 whp)


i recommend you datalog and check if everything is running well

Almost 150wtq is already insane. On the street that low HP increase may not even be noticed.
