we have done everything you are talking about doing to my brothers truck along with .120 lines, .120 holders, full cuts and 5x18 dual feeds, 22* timing, CDS 5k springs and idles perfect no lope smooth as silk. I really figured it would lope with all the restriction removed but it dont. As far as afc tuning goes, me and a couple of the other posters have already gone around on that subject and i dont want the argue on this but we removed our afc to get the most fuel possible and it is smokey if you stomp it all the time, but you can allow your foot to be the afc as be easy on the pedal until the turbo starts lighting. But most people wont drive like that so if that is you, you might want to do the tuning way. just my opinion though. Tim
