BMW G11 730d removing Power Reduction SA 843

[zo0rdiac]

Hi Guys, i have a BMW 730d xDrive with the Power Reduction Option 843 which brings the car from 265hp to 211hp. It really sucks to drive a 2t car with that low power. 
So i wanted to remove 843, calculare SVT and TAL and flashed the DME but it doesnt go to 265hp it stays at 211hp. Am i doing something wrong or do i have to reset working hours? 
Thanks
