Predator 212cc horsepower calculator?

#1
Ok so I have a 212cc preadator nonhemi. And I have upgraded it to stage2-ish. I know there are a lot of jackshaft and top speed ratio calculators. But what about an upgrade horsepower calculator. Maybe someone with a little bit more knowledge can calculate it for me. Mods are:

Dyno cam - mod 2 cheater cam
18lbs valve springs
.028 jet
high flow air filter
