i like this write up. Currently have a bmw 640i N55 making 586hp on race gas. Recently bought the Precision 6266 with top mount manifold by JP Werks. Swain Tech is going to coat the manifold. Have the V Wastegate but was looking for a dam BOV. You answered that question reading your post. You have an IG?
