i am!
at the flywheel.... ha ha
nah, I think we have too much power train loss to ever get that without modifying or upgrading some of the engine components itself: bore it out, sleeved, stroker, flywheel upgrade. not just from bolt-ons. I was able to get 280HP out of a 1.8L GSR engine without FI so it's not like it's imposible. there are NA tuners out there.
I think most people with every bolt on option plus tune don't get passed 330 (may come close)... i mean unless it's some BOMB-*** tune with like gen 3s, test pipes, full exhaust, maybe a lightweight flywheel... you probably could.
but I think it's safe to say making up an almost 50-60HP deficit is a pretty tough feat with just bolt-ons. like I think the intake and the test pipes bring the most out and that's only like 20, then with a tune to like 30 hp or something...

I know of a dyno shop locally that claims to measure bhp from his chassis dyno (don't ask me how) where modded G37s dyno'd 330+ hp all day.
Dyno numbers should not be taken religiously, they're a before/after comparison tool nothing more.

An example of dyno numbers taken religiously
You do know your diff also has a gear ratio reduction right?

it might be possible, this guy is almost close to it and his car is not fully tuned.

I agree the dyno is generous, but I think the way he explained it "Stock" on the sheet means stock TUNE with all the bolt ons. So, the dyno sheet is showing three different tunes with the same bolt ons. SO all the bolt ons resulted in 304 and the better tunes got him into the 320+
