I purchased the AEM v1 off some website and I thought it was the v2 for some reason..... The prices were right for the v1 but I'm just curious if there is a big enough performance gap between the two to return it for the v2?

 

Well if you want to return go for it. Personally its just sound difference to me but people say they feel it on the butt dyno. Up to you though.

 

Ok maybe you could elaborate on that. How does it sound different? Is one louder than the other? I would like a quite intake with some decent gains.
