High rpm bog out issue

Okay so I have a 91 fc with a Na 13b with a street port when I take off first and second pull hard and run good but after that I start getting to the top end of 3rd Amd it boggs out and does so in 4th and 5th I can ease the throttle and Cruze no problem but if I give it to Much it Boggs but doesnít die I unlplugged the top injectors and the car still ran ? Is that normal? do I need a tuned Ecu? Bigger top injectors? Someone please help Iíve been throwing to much money at this thing because the body is so clean and it runs great besides that

When you say, "bog," what exactly do you mean. If the torque just kinda dies off at the top end, check to see if your 5/6 port actuators are functioning properly. If they don't open correctly the engine will starve for air at high rpm.
