Well after a couple hours of searching I've stumbled across the stickie that was posted right at the top of the page and going to pull the pc3 and check every thing and see if it clears up

When it's running, put a thermometer on the headers to see if their all the same temp. If it ran fine before, double check all wires/connections, hoses, gas tank vent hose ect. Also double check your coil connections. It will not fire on all cylinders if their not connected correctly.

Good idea to check the pump. Most of the issues I've heard of with the pump are low power in the upper rpm range.

Random thought, did you set the idle speed with the adjuster. Not sure If an 05 works this way, but my 06 has a manual idle adjustment knob on the left side under the tank in the fairings. Previous owner did not know about it.

i finally figured it out turns out the previous owner replaced the fuel pump and when he did that the plastic clip that is on the pump that holds the regulator on was installed incorrectly it would not even allow me to get the pump out of the tank so i forced it out thinking worst case i just put a pump assembly in so once out i noticed the regulator was at the bottom of the tank i grabbed it put it back in place re installed the clip correctly and locked it in with the metal retainer buttoned it all back up threw in some fuel and bam runs better then ever.
