the second o2 sensor shoulkd have no performance effect at all, just an obd2 thing, it will just show a cel. you probably had the fuel trim code due to the first o2 sensor going bad because thats what will give you your fuel tim readings. use your logger to determine the problem becaus eif it was shot, the o2 trims would be going haywire when under full throttle. id replace the first o2 sensor and see if it helps.
