Default tranny install and tune ?????

when i got my built tranny put in my car it still had the 2.73 gears and they tuned then. After the tune they put the gears in it which are 3.42. Would them tuning the car with 2.73 gears in it mess it up when the 3.42 gears went in...Would the tune be messed up...
