I took my F10 535i to EAS and had it dyno'd today. The results were shocking, the HP was lower than I had expected but Terry said that 90 degree weather doesn't help. But the Torque i'm putting out is about 100ft/lb over stock which is great.
My mods:
RSi catless Down pipe
Megan Racing Axle Back Exhaust
JB4 Stage 2 tune (map 0, map 1, map2)
91/100 octane (50/50 mix)
We took a total of 7 runs and here are three of the best. We tried out map 2, map 1, and map 0.
Map 2 (14.5psi)- 297.98 whp (375hp crank aprox). 365.95 wtq (446tq crank aprox).
Map 1 (12.5psi)- 298.97 whp (372hp crank aprox). 347.91 wtq (424tq crank aprox).
Map 0 (stock boost)- 287.59 who (359hp crank aprox). 304.91 wtq (372tq crank aprox).
