So I've been reading about many of you putting on a 3 Stage Intake Manifold and getting an AA tune to get some extra power, which I'm looking to do very soon. I used Gavin@MMW's link to make sure that I have a N52, and then used MOTO69JOE's link to read the specs on the N52. In the specs it says that the N52 already has a 3 stage DISA? intake manifold. So what 3 Stage Intake's are you guys using and where do you purchase them from? If this is mentioned somewhere in another thread I'm sorry but I haven't found it. Thank you for any information.
