I've seen great numbers at 8psi, but never though a 2.0 would bang out 475 and 15psi. Is that a hell of a tune, or am I naive in thinking that lol
I am in the same boat as you. I had always understood (or maybe misunderstood) that they were not very boost friendly.

People have made 700+ whp on a completely stock F20C (might have been an F22C).

They're incredibly stout motors. 450+ on pump gas, daily driven, is common. Hell, even supercharged ones are getting around that 450 mark on stock motors.

I like things that work well, not things that don't work well but are different than what other people are doing. I'm funny like that.

VTEC engagement RPM needs to be changed too, that power transition is ugly but that's easy to tweak in software. Who knows what it looks like at different load though, it may be perfect on the street at not-full-throttle.
You would think the almight Jeff Evans woulda fixed that, I wonder his reasoning.

Glad im not the only one who thinks this is dumb.

You're not the only one that thinks it's done. I just posted it because it was different. Different doesn't always mean good. I would have went with a single, and called it a day.
