Paxton supercharger

I am nosin around again! I want to do something different?
I think I can afford the Paxton set-up, Carb and Methanol kit.
Why did you go Vortech vs Paxton or Procharger? I am always forgeting to turn my fuel pump on/off. Leaning out my motor is my last hurdle
An O2 sensor was suggested?
What about a fuel pressure switch that shuts down the ignition???
This would solve the problem of a fuel pump failure or bonehead mistake.
I drive the car on Road racing courses so I might not visually notice a problem denoted by the fuel pres. guage quick enough.
