Jerky start MS43 M54B30 FW 10.72

After update from 10.67 I started to experiencing jerky start. This is not my only problem because I am still having some problems with reductions to 2th gear that results in a little kick in the back when comming to close stop. So I decided to copy values from newest petrol map following tables: Parameter Gear Up, Parameter Gear Down, Cluth Slip% Correction Start Gear, Pres. TQ. Lookup Cor., Lookup Slipt RPM. Sadly after adaptation reset and doing adaptation noticed no difference.
I am attaching my map with logs.

Bonus question in my last post I got infrormation that cruise control should be working on MS43 but it is working only to 5th gear and when speed is lower than 50kmph?

Same here after upgrade to 10.72 . Also on MS43 . 10.67 was much smoother .

I think that 10.67 my gearbox on ms43 and m54b30 was also more cultured and calmer

I had Lukasz remote-in and did a quick live tuning and fixed the "kick" on coming to a stop. I can share my map if needed. M54B30 with MS43, FW10.72

I also get a slight kick in reduction to 2th gear when coming to a stop. If you can share your map and we compare it to the your original posted map we should be able to see the changes.
