After talking to my machine shop I have decided to increase the compression on my 1.6 16v, they think that the connecting rods can take the abuse after they work with them a bit....but the thing that I worry about is my fuel system. Will I have to run bigger injectors or will I have to do ECM remapping or anything like that? Has anyone ever done this? to do ecm remaping or anything like that? Has anyone ever done this?
