1.0 TSI Engine Power Outputs

[ColinStone]

Just a query about power outputs of the 1.0 TSI engine.
My 2015/2016MY Golf has a 85kw 1.0TSI variant. Now the output of that engine has been dropped to 81kw. I wonder why?
Has the engine changed from the Otto cycle to Miller cycle?? Or something else??
Anyone know??
