Alright guys, I understand what a window switch does, but if you miss a gear, and then slam on the gas like you would normally what happens?? Is the nitrous still cut off because it's only set to spray up till like 5500rpm??

 

yes, exactly

 

Good to hear, so essentially with a window switch, are there any risks at all with nitrous??

 

virtually none. even w/out it , and not being stupid it's really safe.

you could still lean out, but w/ the fp safety switch that pretty much eliminates that.

 

How much do fuel pressure safety switches cost?

 

they are cheap.....$35 or less

check this one....
