i have an 03 ram with the hemi...whats the difference between the 3714 and 3715 superchips programmer and should i be getting one over the other?

i was told that the shift points cant be adjusted but the rev limiter can........if you raise the rev limiter wont it shift higher any way?

 

i only see the 3715 for your truck.
The Rev limiter is there to stop your engine from blowing. So if in WOT, you won't over rev your engine. It should enable u to adjust the shift points for 1st to 2nd, and 3rd to 4th.

 

3715=3.9L, 4.7L, 5.2L, 5.7L, and 5.9L
or
3714=Hemi 03' specific
Did not have transmission adjustment.
Only rev and speed limiters.
