Well SNL Performance in Ft Worth isolated the problem....i hope. They disconnected the aeromotive billet fuel pump speed controller and the Autometer tach adapter. Basically running the eliminator pump at high speed with out the speed controller and could not get the PCM to kick out the P0606 code at all. When ever the speed controller and tach adapter were still wired in but still bypassed with the manual bypass/override switch the code and limp mode happened everytime the throttle hit 75%.

Aeromotive has been great thru this whole ordeal and is sending a new speed controller.

Today, it was determined thru talking with the 5th gen expert at Autometer, that the signal from the coil wire to the autometer tach adapter had too much voltage/noise? Autometer was aware that this was an issue on the 5th gen but not on all of them....it is sporadic.

Autometer is sending a capacitor to wire inline to eliminate the interference with the PCM. This in combination with a new speed controller hopefully will allow this fuel system to feed my motor the way it should.
