Hi All,
I just tried racechip ultimate on my 35D, the throttle response improvement can be felt right away. The increase in performance is not dramatic, but definitely can be felt. I would say it improves the drivability in comfort mode the most. Before it felt sluggish in comfort mode.
However I do find the engine sounding not as smooth as stock. The diesel clatter is much more pronounced. I'm at default E0 setting. Has anyone found a setting that gives performance gain but still close to factory smoothness? That may be too much to ask, but just thought I'd check. I have not tried other settings yet.
