40 tfsi and 45 tfsi in a Q3.

[DarkMatter]

I'm thinking of buying an Audi Q3 (2019/2020) and am looking at the 40 tfsi and 45 tfsi petrol engine options with DSG gearbox - are there any physical differences between those engines or are they just mapped differently, in which case can the 40 tfsi be re-mapped to give the same performance as the 45 tfsi?

Are there any differences in the DSG gearbox maps for those two engines?

Thanks.
