VTECWITHBOOST

i am running an h23a1 in a 94 coupe. it runs fine and pulls like a bat out of hell. the only thing is that it runs kinds rich. i have not hooked up any of the egr system and have no cat on it. of course i got a check engine light on but i am used to it. i tried 95 ls ecu hopping that i might run ok but the car bucked all over the road. i have read that some people disconnect the egr on turbo ludes but how do they get around the cel??
