VXOC Astra-J/GTC

Hello guys.

I am sorry if someone already questioned about this. So i own Astra J 1.6 turbo SIDI 170hp with code A16XHT. I wonder if the "updated engine A16SHT with 200 hp is the same , but only different software. I talked with a guy in the local dealership and he told me it's just software " these extra 30hp" . Sooo, can somebody give more info about this .

So hello again guys. I've made software tuning on the 1.6 turbo Sidi A16XHT( stock 170hp).I'm uploading diagram if someone has the same engine and wants to know how the engine performance is after the software. On the graph you can see the so called "overboost" by Opel  is up to 4500rpm.
