Opinions for speedo recalibrating

After a morning of phone calls ive come to the community for help. I have an 06 Rubicon on 33s and am looking to re-calibrate my speedo as it varies from 5-12 mph off. I'd also like to do it for an accurate gauge of my mpg as I reset the trip counter every fill up.

So far I've heard:

$400 - flashpaq + $42 labor, from an off-road jeep specialty shop.
$0 - Jeep dealer in town says they'll play around with it, but can't guarantee a fix, hence the free part.
$170 - procal + free install, a different jeep dealer - this is wrong as the procal is for JK only after I researched it.

I've also read good things about the speedohealer which is about $100 and plug and play.

So, has anyone had this problem, and how did you fix it?

Speedo healer. It gets great reviews from members here. Also, like you said, its plug and play. A tool like that is the only way to do it since the rubicon uses a tone ring. I am about to jump on one soon for my super short.

Another vote for Speedohealer. Easy install and accurate.

It's really nice as it changes by percentage, not MPH at a given speed. When you move on to bigger tires, you can adjust it again to make it accurate again. At first I thought $100 was a lot for it, but for what it does, it's worth it.

Plug and play version is not because the speed sensor uses a different plug but the cheeper version that is wired in by installer works fine and is cheeper

On my 98 the super short SYE I had used sensor with a different plug so I bought the cheeper mortorcycle version that has to be wired in. works great

Uses 4 wires
One to Ted into current sensor ground
One Ted into current sensor 5 volt supply
Lastly sensor signal wire is cut with sensor connected end to speedo healer input and harness end to speedo healer output
