I know this has been beat to death, but lets beat it a little more

I want to get a programmer but not sure which is best for me? I Have 37 mud grapplers but may switch to 35s all terrains for weekly driving. I have 4.56s gears and no induction upgrades (Should I?). I have a SISO Flowmaster mostly for sound. I want to be able to adjust for Tires (Switch from 35s to 37s and back) for weekly and weekend driving and want my speedo to read correctly. I would like to hear everyones thoughts and opinions, please.

Thanks!!!

 

with the edge you can adjust all that stuff including the tire size and gear ratio.

 

I'm happy with my X-Cal. The thing is you'll get an equal number of responses one way or the other so asking that question here has a foregone conclusion.

In the end you wont have a decisive side and you'll need to just pick one and go with it.

I'm sure you'll be happy with whichever one you get.

 

I'd say get the Edge, its worked wonders with my truck and you can monitor all of your temperatures.
