I only notice it on low speed corners, ie 1st or 2nd gear stuff, add any loose gravel, or rain, and it's really really noticeable

What is it you notice? The only thing I notice is that the DSC cuts the power which drives me insane. But, if I go to DTC (e-diff) it seems fine.

The reason DSC is cutting power is because the inside wheel is trying to spin as a result of not having an LSD. That's really the whole issue.

But, with DTC enabled I don't really have this issue. It is a pain to have to engage it every time you start the car though.

As I said above, it would be nice to have it but it's not a big deal to me as I don't track my car and the situation above doesn't happen that often.

The DSC shouldn't be cutting power untill the wheel is seriously spinning or both let loose. DSC does Brakes first, then power. It won't e-diff but it "sorta" will.

If your loosing power your foot is way too far down for the amount of steering lock. But in a 135 that's easy to do. Remember the string technique.

mine cuts power at the slightest wheelspin, the whole brake before power cut must be so fast I never notice it

there's a couple corners I do every day, I turn off the nanny in advance, because it's almost got me killed (cutting power while I merged onto a busy highway), and turn it back on after I'm through the corner

Same here.

I think the goal of the DCS is safety, not speed. It seems to me like it cuts power before it ever trys to transfer power to the outside wheel.

Yea the trottle is pretty sensitive in the 135. Maby they also have the DSC turned up more in it too.

In the 128 I can get a good amount of slip before the light starts blinking and I feel anything in a turn. I can actualy get a little snap out of it. But then I don't hit 300ft/lbs at 1400RPM
