Welcome back to the land where loud noises don't make you duck, and thanks for your time deployed, Brother!
Before you gt too carried away with the CAI, you MAY want to read this thread:
http://dygytalworld.ehost-services13...read.php?t=340 Bill has stated more than once that the commercial CAIs may not really give you what they're worth, and this is a REALLY cheap alternative - that won't make your engine run lean.
I'm sure the Gryphon can help/cure the throttle hesitation problem, but I don't know why you'd still be having problems from a possibly bad tank of gas? I'm more in the camp of "winter" blends causing your dropoff in mileage. Be interesting to see what Bill has to say, when he surfaces.
- Jack
