So mods are in the sig except for I just put on an ETS intake pipe to mate up with the maf and apexi filter. So like the title says I have the stock IX bov but that thing is extremely loud now! Couple things, I do enjoy the sound but its almost like a flutter, when I go thru the gears it does'nt seemed to pull as hard in lower rpms, and last but not least when I am cruising at say 80 and I quickly let off the gas if def. hesitates. Now my car has been tuned twice and I knew that putting an intake pipe could make change but not make it that loud for one and most importantly could cause idling issues and acclearting issues like that. Does it really make that much of a difference especially with the acclearting and idling, damn I need a tune quick! Aside from that ETS was outstanding all the way around, my 3.5" IC will be here soon!

 

maybe u got the bov backward Like you said get it tune

 

Will check the bov placement I was in a hurry!

 

Intake is the main Mod that needs a tune! +1 for ETS.

 

Check to make sure its not venting into the atmosphere that will cause idle problems and make it alot louder.
