I do not mean that you have the injector clips for the individual location reversed but may, point-in-fact, have the secondary injector clips hooked up to the primaries and the primaries hooked up to the secondaries. (Don't ask me how I know that could be a cause of those symptoms)

Dont the secondaries activate after i think 3200? If that was the case then the car shouldnt even start?

But the 'primaries' (in the secondary location) are firing.

The issue comes to the fuel injection blending going on. When you floor gas the 'primaries' in the secondary location are unable to keep up with the air flow thus stalling out the engine. However you can creep up the RPM range if you don't floor it as the injection doesn't get 'out-flown'.
