Yeah I think you need a 2nd opinion here- if you look at the origins of the GTS engine, it started with 400 hp and then with intake/cam changes gained 30 hp. Then it went up another +10hp for the 2014 models. Sitting at 440 hp, I'd bet a tune on a NA engine is only gonna get you another ~ 10-15 hp.

No way to get more than 15-20 or so HP on a good day out of a N/A engine with just a tune.
Unless it's something like a C63 with 6.2L where they de-tuned it from the factory.
