This may sound stupid but was wondering about the gear ratio adjustment on the tuner have everything else pretty much maxed out but have never touched the gear ratio my manual on the truck states 3:55 and that is what the tuner is on have been Leary of touching the parameters or it just wouldn"t work with an 05 dakota to go past 3:55 unless i have changed gears themselves. thanks

 

if you have 3.55s dont change it.

leave it at 3.55s

 

the only thing that does is, adjust your speedometer if you change gear sets, only thing its good for...

 

X2, you are correct
