The stock 1g blow off valve is fantastic, and the odds of a blow off valve under 75 dollars being better is pretty much zero. They even sound alright if you vent to the atmosphere.

The reason you shouldn't vent to the atmosphere is because the car will die after you go into boost and blow off. It gets too rich because air that has already been metered (measured) gets expelled to the atmosphere. It happens on *most* DSM's that try to do it.

The AFC Neo has something built in that is supposed to remedy this issue, but I have yet to hear anything good or bad about it.
