I am in the process of rebuilding the 4.6 in my 2004 Disco. I am doing some performance mods while I have it torn down (nothing wild) and I am very interested in bypassing the secondary air system in a way that will not cause fault codes.
Has anyone figured this out yet? The hardware would be easy....ie. plug the secondary air passages on the heads but I am unsure how to keep the computer happy afterwards.
