Yea, I really like the WI.  I'm actually going to larger jets this weekend
(2-1mm aquamists from 2-.7mm)

The largest thing I notice is intake temp drops when city driving.  Like
when you sit at a light and your engine gets heat soaked, the WI get's
things into check real quick if you have to go WOT:)  You'll also notice
good gains if your running a stock IC.  I haven't really been able to add
extra advance beyond what you normally do for cooler temps like some people.
That's why I'm getting the larger jets, hopefully I'll be able to add a 3-5
degree's of advance when on boost.

Here's the system I reccomend for starters

100 psi Surflo pump
Surflo Accumuator
hobbs pressure switch from Napa
Solenoid of some type from Mcmaster.com
aquamist nozzle

The DSM WI group on yahoo has some good info.

HTH,
