As soon as i turn the steering, the torque is reduced at the engine not with braking even in 1st gear. It's really interesting to throw the car in 1st gear while turning a corner and get no wheel spin. I get just enough forward motion to keep tires planted.

Once your moving the vehicle uses a downshift rev match program:
front wheel speed sensors determine the vehicle speed, and throttle is cut to match RPMs.
I don't believe there is a gate sensor on the MT selector. The program assumes a downshift of 1 gear. based on braking?
You could try skipping from 4th to 2nd and see if you can get wheel slip.
-- The Shift program may just be a part of the intervention.
-- I got rid of my 135, and am running a 128 now.
Another option is to run slightly taller rears. then the program allows the rear wheels to be running a little faster (the same RPM on a larger circumference). With this configuration on my 128 I can lose the back end if I don't rev match. It should have a dramatic effect on the 135.
Also an advantage of the tall tire is it adds margin to the eDiff slip limit, as the rear wheels are normally spinning at a slower RPM than the fronts, the program rarely can see rear slip.
I'm running 245/40/17 Front and 245/45/17 rear.
