So alright guys heres the deal im running a stock c26 with 2.5 inch piping with a 1g dsm bov.Ive also got a 3" downpipe and my boost pushed to 10. ive learned that venting to the atmosphere is cool and all but its not better performance wise. It runs ALOT better when recirculated and actually idles like its supposed to but my problem is that when it is vented to atmosphere in between shift it stutters but when its recirculated it makes a badass sound as my bov sound but i investigated it a little more and found out its the air coming back out of my intake.(as if the air is getting pushed back through the air filter the opposite way it sucks air) so guys im turning to your AWESOME advice because its stumping me haha thanx all.
