    Finally rolled my 91 Miata with Corky's Warner-Ishi Turbo into the shop 
Saturday.  Corky modified the fuel pressure regulator with an improved 
diaphragm support plate and drilled a vent hole into the formerly closed off 
chamber under the diaphragm.  Completely eliminated the tendency to run rich 
and improved the response of the fuel system (I'm tracking the fuel-air 
mixture with a ratiometer on the steering column).  I like dealing with Corky 
and learn something every time I talk to him.  He stands behind his product 
and is a pleasure to deal with.  
    For those who are replacing their air filters at the dealer for $25 a pop, 
buy a K&N air filter.  It costs $40-50 US but lasts the life of the car.

outdrag my Miata!)
