Either name is right... stutterbox or 2-step or 2-stage...

I know I'm starting to sound like a broken record to some people... but have you tried boost leak testing it? If you're losing enough air anywhere after the turbo, your throttle response and spool times will go down the tubes. Technically, none should be lost, but that's difficult given the size of most turbo intake systems. Everything should be sealed up TIGHT!

I know I told you about windoweld at the track for your mounts, but given the amount of time your car would be down (unless you had another set of mounts), I'd go for poly mounts instead. They're actually pretty cheap. Especially if you just use the inserts because you wouldn't have to press out the bushings in the mounts that you already have. Poly motor and tranny mounts help substantially with wheel hop. At least they do with FWD DSMs. I don't know how a FWD Honda would be different, but for $30 a set, it's worth a try.
