On our 2015 320xi, we added BM3 stage 1, transmission flash, awe cat back, Injen air intake, catted downpipe, and charge pipe. Dyno clocked it at 251.36 hp and 297.97 lb tq to the wheels. Subsequent runs had slightly lower hp and slightly higher tq. 0-60 per dragy is 5.95 (5.60 1ft roll out) with zero engine loading...just stomp and go...and that's with two people in the car on a half tank. Based on an online calculator, we estimate 311hp to the crank, but realize this conversion is often debated. RENNtech estimates a 17% loss for an automatic all wheel drive MB based on their experience... Hope this helps...
