I an a newbie that is in need of a little advise 1985 635Csi accerelerate nicely to abiut 4000 RPM then get a surge almost likr\e the old 4 barrel carbs user to do. I would like to have that power through the entire curve not just at the top. Is this the way it is supposed to act? Thanks to all who helped me out with the fuel pressure regulator.
