Have some of you, friends, any experience with a multi throttle intake manifold installed in a 328i. I'm thinking about to buy one from BMP Design (http://www.bmpdesign.com/products/acc/engine/multithrottle.shtml)
Please let me know if this mod will do the job by itself or needs additional mods. How much power gain will the engine have?
Thanks so much
