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,
