Acceleration on 2012 E63
Yes for those who ask, I had the traction control completely disabled. I even brake torqued and barely got a whimper from the rear wheels.
Is that what others are getting? I am new to the Biturbo
Edit: Are others getting any wheelspin just stomping the gas in the 2012/2013 E63 biturbo? I live at sea level with Temps in the 70s this week. You won't find a whole lot better environment for cars than here and now.

What is your trap speeds at that 12.2? I could do a 12.2 with my old 55 stock...
I'm taking it in this week to check out the turbo performance code that comes on from time to time, after which it's going on a dyno to confirm that I do have 550bhp.
What are the P30 performance pack guys getting on the dyno anyways?

My stock P30 was smoking tires without the tune. I would suggest bring up to 39-40psi on the tires. Do you have the stock wheels and tires?

2 - Push the gas pedal all the way to the floor (past the click point) and hold it there for a minimum of 5 seconds.
3 - Still keeping the pedal all the way down, return the key to the off/"0" position.
4 - After the key is in the "0" position you can let the pedal up.
5 - Stay in the vehicle (don't open any doors/windows and leave the radio off) for 2 minutes. You should hear something whirring from the dash when it's done.
Dealer will be sending ecu off for Renntech tune after I get back from out of the country, should make things a bit more interesting
