Pulleys vs boost levels
I read about the 174mm pulleys, 180mm pulleys, etc., but what boost levels does each run? The reason I ask is that when I bought my E55 a year or so ago I was told it had a Renntech pulley, and my gauge shows that it is running 12.5 psi (I have headers as well). Would this be the 174mm or 180mm?
