I used to have a turbosmart bov on my car with the spring set to "hard" i used to get a fluttering noise when backing off under low loads.I now have a stock bov which runs better but has a gay shhh to it.Now if i blank off the stock bov and run the afm on the i/c piping will i get the vl sound of "po po po".Ive heard that running the afm on the i/c is better as it gets a reading of the air flow ,temp after the effects of the intercooler.But mainly i want a more aggressive noise for the cool factor .Mods are 14psi,pod,large fmic,safc on a rb25.
