Lag from dead stop
I have owned my 08 335i E92 for a couple of years now and one thing that has always bothered me is the huge lag it has from a stop. I read another thread on it from 2010 and everyone was giving him $#%^ about traction loss, turbo lag, heavier car, etc.
As far as I can tell it seems to be more related to the dtc system. In drive from a stop, you might have a 1/2-1 sec of delay from the time you hit the throttle till the car starts moving. Holding the brakes with a little throttle/rpm to spin the turbos up doesn't seem to help either so it's not turbo lag.
Dropping it into sport or M1 doesn't help but turning DTC off seems to shorten it some. It is very frustrating but it has always been this way.
I'm putting a JB4 on it next week but I don't expect that to make a difference. Have read about the known lag problem here but not sure if it is related.
Any intelligent suggestions? TIA
