2015 M3 VBOX/Trap Speeds - Stock & BMS Tuned numbers inside

From another website~

"Hey guys,

Was able to swing by a private track for a handful of VBOX passes. I did two passes stock and one pass with alpha tuning in place -- just to see where we are at. All runs were done on E20 fuel, temps in the mid 60s. Boost on the OEM runs hit around 17psi, and around 23psi on the tuned runs. Note I didn't launch hard for any of the runs as the car only has 250 miles so the ETs are garbage. Traps are telling though. The files are posted via the vboxtools.com site which averages the last 60' of the run like a real track would.

Net result was ~118mph stock and ~124mph tuned. The funny thing is the tuned run would have been faster had it not been for DTC kicking in after each shift. With some more massaging I think 127mph 100% stock with E85 will be possible."

ridiculous! Congrats to Terry!

E20? I kind of want to see fuel trims to understand the fuel headroom this motor has.

Too bad it could not have been a completely flat run , but still impressive gains . Did you happen to get any 60-130 mph data ? Thanks for posting !

118.7mph trap with DTC kicking in on shifts? Impressed this is a ~119mph car stock.

Once again BMS is setting the bar. These results make me want to get one....real bad.

IBT: these results are fake. look at that .7% slope. oh now he is on E20 cheating.

To be fair the modded trap speed should be reported at 125 mph (rounding up, since you are using no decimal places). A very nice gain!
