Yeah...I'd say rev limiter as well.
The EEC-IV shuts fuel to the injectors at 6250 rpm. Also, if you don't have quality springs in your car, it's likely that you're getting some float before you even hit the limiter after about 6000. When your valves float even a little, raw fuel gets dumped into the exhaust system causing the O2 sensors to signal a rich condition to the computer which will then go into a full-lean metering to effectively slow the engine down. If your tach is off a little, you're probably hitting the rev limiter. Otherwise, I'd guess it was springs. You've got plenty of fuel capability there with the 190lph pump and 24lb injectors, so I don't think that is the problem. --nathan
