Default calibrating speedo

im sure this has been posted before but couldnt find anything

how hard is it to calibrate the speedo, i went form 3.42 to 4.11 and when the speedo says 90 im going 75, wouldn't be a big prob but i just put 100 fake miles on the car lol

would i be able to do this myself? or would i be able to take it to a dealership and have them change it without effecting my tune? anyone know what they'd charge?

posted this in the diagnostic section but didnt get any feedback

Go back to whoever tuned your car and they can reflash the computer and make the change for the 4.11s.
