We use a 130 ramp rate on a dyno dynamics if its any consolation to anyone.
The pic in my avatar is me during a superlap event.

Damn that's a nice pic! Nice car too of course.
Part of it might have to do with your altitude, or lack thereof haha. I live above 6000 feet, so our HP numbers are considerably lower. I dyno'd mine at 318 at altitude, but corrected (supposedly at sea level) was 403, at 6700RPMs at15psi in 3rd gear. That was on a Mustang Dyno too, and they're known for having lower numbers.

I'm also getting the manifold and DP, both with a lifetime warranty, a Tial 50mm WG, and I'm paying extra for the WG rerouting to DP and ceramicoating everything. So I think it's well worth it.
Where those ones you've seen the HP model or SP model?
I've pretty much decided to go with the GT500R-SP.
