If it's that new you might end up needing to replace the ECU, in which case you'd probably be cheaper trading in for a bigger engine. There's an argument that says if it's that new that argument wil stand regardless of what needs changed.
First thing to do is grab the sales brochure. look at the spec sheets at the back - if the 9.9 is the same bore & stroke a something with more HP and siomilar weight / bore /stroke then you stand half a chance.
If, however, it's the "big HP" engine of a batch of two or three smaller ones then forget it....unless you just want to do it for the challenge.
