        ok i have a similiar pulse. and engine gorunding kit helped that out. if you are also runnign rich take a look at you coolant temp sensor. (the green one, $52CDN at a mazda dealer)
        When you turn your car on... does it return the favor?

        With much too much boost,
        And drove a rod through his block.

          Doesn't seem like motor mounts would cause THAT much jolting to me

            yah it feels more like the TB is opening and closing on its own. even when i let off the gas in 1st gear and just cruise at 5mph or whatever it is itll jolt back and forth. its not gonna be motor mounts, somethings just not functioning right.

              could be either your front, rear , or passenger side motor mounts.
              or it could be your axles...
              I noticed this goes away when I change my axles.

                    yah i tried looking for that too. i really dont have much rubber hose besides on the intercooler and to connect all my pipes, so i tighten my hose clamps hardcore and still does it. i can build 11-12 boost without a controller so its obviously NOT in the piping after the turbo. maybe ill look closer at the piping before the turbo.

                      also a bad seal at the cylinder head and engine block will give you a leak that will make your car idle up and down....like your tb is opening. could mean a bad head gasket.

                        my idle's pretty stable, its the letting off the gas part that gives me that shake. but i just recently replaced my cap n rotor, i gave out on me yesterday and it's been a lot better ever since.

                          you better change that bad cv joint also ...
                          If it gives out on you . your stuck where ever you are.
                          I guess if you have an LSD you may be able to creep home
