If I were to go back to the stock tune, and vin-unlock the superchips, would it reset any speedometer adjustments I had made?

 

i suspect that it will restore all the stock parameters, including speedo. but try it and see.

 

Yeah, the reason I ask is that I was thinking about putting it on ebay as a buy it now for some quick cash. I really don't want to though, I really do like the superchips.

 

Yeah, it will reset it.

 

Been there, tried that. Both of my vehicles are lifted and have larger than stock tires. My Grand Cherokee Overland has the 4.7 HO engine in it and a completely different factory tune than the standard 4.7. I understand that the SC gives no performance benefit to the Dodge HO tune, so I can't justify the cost of the tuner just for speedo recal.
Was a no go...
