That's the chip I'm running right now and I like it a
lot.  It's forgiving of octane fluctuations when I
travel, no pining even on 90.  Decent power and nicer
linearity of the throttle compared to the on/off of
the later MTM chips.

The RS2 manifold is the hard part of the full RS2
install, so having this done is nice.  The main
benefit is in exhaust gas movement from the #1 and #5
cylinders, which tend to burn exhaust valves with a
chip and stock manifold.

The only concern I'd raise is that if you plan to
upgrade to the RS2 turbo and another chipset, you'll
need a 3 bar pressure transducer which are getting
very rare and pricey.  Other than that, I'd say you're
looking at a great setup.
