ecm issue or?

ok just switched out a turbo set up and went back totally stock. pulled the tune chip out with ecm out of car and battery was 1st thing disconnected. now for some reason along with many other issues the idle wont stay the same and idles a bit high with clutch out and levels down with it in. tried adjusting tps and idle screw and still the car acts stupid. swapped ecm with 2 others from running car and also the map sensor. who'd though going back would be so aggravating. car ran perfect with the twins and idle was completely smooth due to motor was bone ass stock with only what it had to have. car is only a cruiser and never saw a race, just like the sound of the blow off. bigtime waiste. let me know your thoughts and suggestions. thanks
