Craig, that's not "exactly" correct. Be careful, I don't want to get into this with you on a public forum.
The andial I saw work had several pulse settings. You pick a setting and it would run the frequency valve at a different percentages. But like you mentioned, not vs a variable boost/RPM which is what we need/want which makes it not much more then a bandaid.
Dan, I see your in Bellingham. You ever make it down south???
