    It does lack power...once i hit 16,17 rpm, it won't accelerate even if I hold the pedal to the ground. It won't accelerate until I shift to the next gear but not with the same power

    When was the last time you replaced fuel and air filters?

    What is a limit of RPMs if you hold the pedal to the ground on the first gear.

    I don't remember how engine brake works on prehistoric Celect engines: by engine speed or road speed. Probably by engine speed and in this case you need check your CC on a highway.
    If CC is ok - a problem with a fuel or ECM internals (not enough a double positive potential for MOSFIT output injector drivers which is very common problem for old Cummins ECMs or something else inside of a black box).
    Plus, you didn't answer to NorthernMechanic on his question about fault codes.

    It could have two. One for speedo and one from ecm or a four wire sensor. I would start there.
