I'm BMS stage 1 with custom exhaust cut outs, and my car did 4 second flat to 60 using the dynolicious app which we were discussing is usually .25 slower... to Firex5 is thinking its a high 3's car..rocket ship for the size

The cut out makes a weirdly huge difference.. theyre right after the downpipes where the resonators were and the throttle response difference is huge. If you mash the gas on the 50i it feels like the engine has even more power and its not unleashing it due to air restrictions or something.. Once I installed my cutouts, and put them on wide open it feels like the car struggles so much less to breath. Only issue im having now is i honestly dont think the transmission can handle anymore power on this car,already having some weird 3rd gear issues when in the city Interesting too, just on the X5M forum and there vbox numbers arent so far off some yours.... 4.0 0-60.. and 9.7 0-100 The 50i shouldnt be this fast!!!!!

i need to remove the BMS tune and drive around for a while. then do baseline dyno with catback GThaus exhaust with flaps open then flaps closed.
then BMS tune a week or two later. my 0-60 using video recorded, time stamp. has only been as fast as 4.3....might have had faster launches but i dont believe i have accurate data.
