This kit was installed 2 months ago on my friend/neighbors car, a 2009 GT.
This is after they corrected the piping.
Car made 407rwhp 450 torque on 6 lb boost. They would have made more, but they pegged the stock maf and possibly the fuel pump and he ran out of funds. He's buying those parts in a week or two. He has an aeromotive 340, so he's just going to get a boost a pump.
