I've read as many posts about this mod as humanly possible(JamesNow vs. Av Mod 1.0, 1.1, 1.2). The majority are specific to the 250F. Have any of you tried out both mods (JamesNow vs. Av 1.3 with 3 plates)on the 400/426/450? If so, which one was preferred and why?
If you've only tried one version, which one are you running? Good points? Bad points?
