    i think that it must be running rich or something, because when i drive it does not pull at all, has no power. it idles good, but when i rev it up it starts to misfire or something i dont even know

    An LS SHOULD somewhere around 175-180 psi. 150 is kinda low.
    "Cool car" less.

    even though 150 sounds a little low it should run fine with that compression.
