im lookin for a atmospheric blow off valve , ino our engines dnt like them but i love the sound of the woooshh! lol. my mate fitted a atmospheric on his seat leon cupra and he hasnt had no error codes. i was wondering tho a dump valve i have seen on ebay is 34mm diameter will this be a straight fit or not? if not what will i need. i was lookin at them turbosmart dual port bov's they look good a bit pricey tho?

the forge split r set up properly will probably be your best bet but alot of cars dont run properly with them on but at least the forge one does recirculate some of the air so you stand a better chance of it working.
