About 5 years ago I was having problems with the lifters collapsing even after installing new ones. I found a website that caught my attention and seemed legit. One sends in the ECM and you get it back within the week. For $50 which includes return shipping. They will disable the AFM mode. Please read in total. This guy researched alot into the AFM and really knows his stuff.

Um why are you putting the same reply everywhere and just joined a month ago. Are you the guy from the link then?
What guarantees do I have from some random person on the internet?
