Re: need help wot 3.73
my friend had a tune from bama chips and later got different overall height tires, his tuner was unlocked so he could modify the speedo calibration without messing up his custom tune, plug the tuner up and see if it will let you modify it. Its done with rotations per mile so you can find an online calculator to find out what it is now and what it should be for 3.73s~ then just enter that in and double check it. You should be able to fix that and keep your tune.
