I don't have any experience with the intake, but
BUT here is another problem... When I start my car, after sitting overnight in an underground garage, it tries to die right after starting it.
I had the same problem, untill I changed my fuel injectors. No more stalling at start up. Actually, now that I think about it my car hesitated wicked untill I cahnged them as well... Might not be your problem, but it's something to think about....
