when you go to purge, instead uf using a purge selenoind, rev up the motor to about 2-2500rpm and tap the no2 button very quickly. touch it and let off, don't hold it for more than a split second. you will see your motor bog for a split second when you do this. you will know the system is cleared when you tap the button and your motor surges insted of bogs.
super302 is right, allows for pure nitrous to flow so you don't bog when you activate the N20. Plus it looks cool
