    So the Zed is doing all sorts of weird shizz..... Go to start it and it cranks over fine, but once its going its not right. If i sit there with my foot hard to the ground it coughs and sputters and wont rev at all, but as soon as i take my foot off it goes up to 2000RPM and then stalls. Blows a fair amount of black smoke... :/ mechanic cousin thinks spark plugs and maybe injectors. Any thoughts?

    So it was driving OK & then this problem occurred?
    Have you checked for fault codes?

    It sounds like you may have blown a hose off somewhere between the turbo & the intake. See if you can build pressure with a boost leak test.

    If you suspect bad plugs pull and inspect them.
