Just my 2 cents. There was nothing in my instructions about an additional hole in the air box. Also there was nothing in the instructions about where and how to install the bracket that supports the throttle and cruise control cables going to the throttle body. It would have been nice to know to mount it BEFORE the S/C was on the engine. It would have been alot easier since there isn't much room.
In addition, there was nothing mentioned in my instructions about attaching the tube on the left side of the intake manifold to your fuel pressure regulator. That was a real b*tch to install after the S/C was on.
I went ahead and had a custom cold air intake made and installed last weekend. No more loss of boost, but I still want to insulate the intake tube from the radiant heat from the engine. All in all, it seems to have fixed the problem of losing boost.
