Took the 2019 E63s to the track few weeks back - quick recap
Best run 10.91 @ 128.6 mph ; now time for some upgrades I guess
That will be incredible if stock!!! Fast as hell either way

We ran a 10.8 with stock ECU and stock TCU, with a CPC tune and BB Intake.
Props for taking it to the track though... it's more than most will do.
Get a CPC and TCU tune to complement your Renntech ECU tune, to open up the torque in the lower gears and then see what she does in the quarter...
