I just did the mod today and it cleared my codes, and I can feel my S/C spool again for the first time in weeks. Thanks for the help. On another note though, a few pages back on this thread, Powerdaze asked about a metallic sound happening at 2400 rpm. I am having the same thing happen and cannot figure out what it is. Does anybody have any ideas? My buddy who owns a repair shop said he read on a tech forum that this sound can sometimes be associated with a KS fault, but after fixing the fault the sound is still there. It is driving me nuts.
