I hope this video can bust the myth of rear mount turbo's being laggy.

Full boost @ right around 3000rpm. (yes that's right 3k!)

'95 LT1 Camaro with 4 speed 4L60e automatic.
Motor is stock and has ~160k miles.
In some of the clips, you'll notice a short pause of the needle before going into boost, this is the transmission downshifting. Other clips do not have this because I manually selected 2nd gear.

Shortly after making this video, I discovered that half the intake manifold bolts were loose and that the manifold was lifting under boost.
This explains why the gauge never hits 7psi and it also caused the air/fuel ratio to richen way up.
