it was a mustang dyno.

tuner was having problems between 2700-3000 rpm. it would go very lean. the car is still having that problem when i drive around. car is hesitating like it hit a wall. anyone have any suggestions ? am i missing some mods ? just seems like the turbo wants to give more. he added more boost but the car went down in hp. need some help lol
