flutter = 25 psi for 1 .a bit years then 20 psi for 1 year = still good, no shaft play. on vl turbo with highflow
usually u put the afm in the cooler pipes and put a metal intake on the front of the turbo for ultimate loudness. and put a pod on or not is up to u. il be doing it tomorrow on my 33 but leaving the afm normal position. u can hear the plastic and doesnt sound as good but my atmo blow off valve still goes off so its like half tutututu half blow off noise. it may go high pitch flutter even through the plastic pipes with the bov hole shut up
