Weird problem. Wont rev past 5000? fuel cut?

When i give my car 3/4 throttle or less i can hit full boost and my car will wind out util it hits the msd rv limit set at 6800. when i give my car full throttle the engine goes on to what i beleave to be a rev limiter at 5000 exactly. Problem just started. i swaped ecu and same problem. Cant tell what is going on.I no the factory rev limit is higher. The msd is in good working order new distributer. Any suggestions on what may be going on. i am clueless i have cheked everything i thought it could be.
