depends what you consider "better".VTA will give you more of the traditional BOV sound, but you'll run rich between shifts, possibly backfire etc.
Re-circ is how the car was meant to run. You won't hear as much "psshhh" sound but the car will be happier running that way. In the long run I think you'll be better off running it re-circulated.

This is your engine on VTA:

Any questions? Actually it's an MS6, but you get the idea. I have read that you can avoid this by relocating the MAF, but otherwise you're going to lose substantial power going VTA.

Damn that's rich. I think the VTA is out of the question. Thanks for the post.

Its VTA normally but, they make kits to make it a recirc. I believe Crossover Auto (http://*************.com/ms3.htm) sells both the Greddy VTA and Recirc and the HKS SSQV VTA and Recirc kits.

Yeah it should still make some sound. Adding a coned CAI or Short Ram intake will also make a "blow off" sound even with the stock one.
