95 lt1 engine tuning problems

ever see a car stay in closes loop and use the o2 sensors to try to change the tune for wide open? My left bank goes dead rich(1 volt) and left goes dead lean (.01 volt) blm starts moving around and pulse with is 25 on one and 18 on the other trying to conpensate for the rich and lean conditions. checked for vaccum leaks actually resealed the intake and put in new 30lbs injectors to make sure I didnt have a bum injector. has afr 190 heads and gm 847 cam. car is flat like a go cart above 4000rpm and that is where is used to take off at to 7000rpm. Dont know what changed but something is way off here. About to start with a fresh bin but dont have a unmolested one to start over with programming. Any ideas???????
