The Turbosmart is a great valve highly recommended from personal use
What makes you say that Faisal?
No it doesn't affect performance, it's not a full atmospheric BOV, it works sequentially, dumps back to the intake at lower revs and blowing off in both directions at higher revs.
not sure if its throwning up any faults so if any1 in my area as vag com let me know.
I'll have to look those vids up from my home PC. I do like a high pitch ptshhh, I can't shake that after being on the Jap Scene for a little while. Mind you, I should wait until I have a map before I decide if I like the noise of the 007 under high boost.
What map are you running Gaz?
