[body]I have installed the XD cam in my brother's '96 Elantra 1.8L. I haven't dynoed it, but the "butt dyno" says I lost some low end power and gained some top end. I'm sure when I get the S-AFC tuned, it'll get back some of the low end power it lost. I just haven't had time to mess with it due to my 70 hrs./week work schedule. [/body]
