Has any one had to test yet? I just renewed registration on my current truck a couple months ago with no drama and no checks of any kind. I am however in the middle of selling it and looking at other trucks. One in particular has DDP 90 injectors, BD Special B turbo, 5" turbo back, AFE intake box, CFM plenum, and a built GB transmission. I am nervous about having to test this truck. I would like to hear from some one that has actually done this testing regardless of pass fail.
