And now I have obtained 294whp (+23whp, so about ~27 at the crank), BUT I have also obtained 297whp (+26whp, so about 30 at the crank) with the Helene filter, which is a simple drop-in. I am not sure if the increase in power was because of the Helene filter or because it was the second run (first run was stock). I didn't wanto to spend yet more money on a 3-rd run with stock filter, but I think I should
Here's a crappy iPhone 3Gs picture of the graph (first) and stock vs Helene (second picture). The fact that the "Helene" run has a bit more torque and power at all RPMs and not only on top RPMs makes me believe that the 297whp (+26whp) is also achievable with the stock filter.
EDIT: I replaced iPhone pics with scans.
