i have a 2000 xplorer sport and i have the xcal-2 programmed with a tune.but in the modify parameters where you can choose your axle/gear, mine is on stock.but my truck has the 3.73 gears in the rear end.should i leave my tune on stock or put it on the 3.73 on the xcal-2? since thats what the truck has.but will it even make a difference? if it don't matter if its on stock or on the 3.73,then i'll probably just leave it on stock.but if putting it on the 3.73 will be better then i will change it. any help or suggestions will greatly be appreciated.

 

The only thing that the gear parameter changes is speedometer calibration.

 

ok.....so should i leave it in stock,or put it for the 3.73?

 

leave it on stock.

 

ok,sounds good.thats where its been since i have owned the xcal-2.thank you for the help.

 

I've put in stock and also set it to my ratio and had no problems.
