Got a 86 RX7 just got it all put together and it idles great throttle is crisp and clean through the whole RPM range UNLESS you Go wide open, then it Studders and acts like its going to die till the rpms drop to about 4k then it kicks in for a sec then drops again.
Now I dont understand how the fuel delivery system is designed. what takes over after the TPS is no longer in contact with the actual throttle lever that actuates it?
For what I am seeing the throttle lever and the TPS are only in contact with one another for just about half travle then from the half way point to full open the TPS is maxed......

What can I check and what can I do????

Additional Information
5th And 6th ports are full open, Actuators are gone and blocked off.
BAC is gone and blocked off.
