Chiptuning possible

Hi Volvo colleagues! I bought the XC60 2011 D3 AWD 2.4 Bi-Turbo with 163 HP. Engine D5244T16! Lt previous owner (first possession) got a chip tuning from Volvo – how and what can he not say more exactly. Now my question – how can you determine if there is a stronger software on it? Does the Volvo with the tester look or do I have to test it? Maybe it was overplayed at the service? My father has the XC60 2.4D with 163 HP from 2008 with 1 Turbo and Chiptuning , that goes after the turbo hole then felt already better to the thing … thought the Bi-Turbo with software would attract rather more intense … it is supposedly up to 230 hp possible since it should be identical to the 205/215 hp D5 … Both by the way are hand switches … Thanks for your tips in advance!
