It's supposed to increase throttle response as well as WOT.

That looks interesting.

Thats what i was thinking, but wasnt sure if boost is directly proportional to throttle position.

Does this also work if you have the power adjust pedals or is there another method for those?

I don't think it does, because they are adjusting to get the pedal off the firewall, those with power adjust can just blip it once away from the firewall and it would achieve the same thing they are talking about... that's my understanding of it anyway
