D3, 2.0l, FWD, GT, 163hp by Heico tune ?!?!

Hi dear Volvo community, perhaps in the near future would like to tune my XC60 by Heico and have following questions to you. Drive the XC60 with the D3 engine, 163 hp, but above all not an AWD but only FWD and automatic and it is the 2.0 litre and not the older 2.4l engine. Now I wonder if the 2.0l compared to the old 2.4l engine is a completely different engine? Now the real question is whether the 2.0l D3 engine with FWD is designed for the Heicotuning on 195 hp and 460 NM, but above all also the gearbox??? With the older D3 and D5 engines it was so that the two were identical and therefore tuning on the D3 was not a problem. The next question would be whether the D3 2.0l FWD has a different transmission than the old D3 2.4l and the D5, thanks?? In short, I am worried that the small D3 2.0l and FWD as well as the automatic transmission for the more than 460 would have been designed by Heico and the other D3 and the D5.
