Okay so I've been putting miles on my Conquest it just started bucking when the car gets warm the secondary fan does not come on but the car doesn't go past half way and i'm not sure if the temp gauge is right. The radiator is upgraded with a thick aluminum radiator but you can't put your hand on it. If i can get pointed in the right direction that could help me , I've got a fuel filter on order i may swap the fuel pump my thoughts is maybe the pump is getting hot and fuel pressure is dipping. Car is on stock boost pressure 7 pounds. it only does it under full boost.
