the reason i scanned it , i was kinda gettin on it for a friend and i just didnt feel like the power was there . plus since getting that scann tool i hook it up when on the highway just to ck stuff out . the left side blk learns are 120-123 right 132-137 if that helps . those are when going on flat ground @70-75

Have you checked the O2s. You should check it first by commanding it lean and see how low the voltage goes down to and command it rich as well to see how high the o2 voltage goes up to. Check response time as well. You might have bad o2 sensor.
