does this sound right?

[jdbubb@ix.netcom.com (Dan Bubb)]

Does that mean I CAN knock it since I have tried it????
It's not digi, but Haltech is speed density. NO intake restriction!
It ain't 35 hp!
I mean come on! You'd have to see a 3 psi pressure drop inlet to throttle
body with CIS to pick up 35 HP by going to something else. I've measured it.
It's less than 1 psi. And the intake restriction on  a VR6 with MAF based
Motronic has an inlet pressure drop of ~.5 psi. So, if you go from CIS to
MAF based digi you're going to pick up ~4% if you do everything right.
(unless, of course, your car's CIS is in sorry assed condition before you
start!)
So, where's the 35 hp hiding in .5 psi inlet pressure difference?
