ECU issue

i have a b20b4 in my 97 cx, and it drives great as long as you dont hammer on it, but when you do like if your passing somebody, it will start running like crap, like its not getting any spark. the b20 is not a vtech, but the ECU thats running it is for a 97 integra, that i believe is a vtech, so when i hit a certain rpm, its trying to kick on the vtech, but since the b20 isn't one, its making it run like ass. is this a good reason for it to run bad? im not throwing any cel codes, i replaced the dizzy cap rotor, plugs and wires, and the ignition coil. and it still does this, but only when you hit like 4000-5000 rpm's. i am lost!!!!
