Have a 2007 TT and are in the process of installing the Alpha 9 kit. My question is any issues with venting BOV's to atmosphere? Have read some threads this causes check engine lights etc. Or is it better for these cars to recirculate? I don't mind the additional noise of venting to the atmosphere. Well not for now anyways. Any information anyone can share on real life experience with this would be great.

That's very comforting. Can't wrap this up fast enough. I'm all about sweet engine tones.

I did not know Forge made those for a 997.1. I would be interested to try them. Any real performance advantage? I also have 65m VTG's. And am Mafless.

I would definitely recommend it for your set up because of the bigger turbos. It holds the boost and won't cause it to leak at 1.6 bar😱! If you have stock turbos , it's not going to do much except for a awesome blowoff noise😀.
