Looking for some insight on what is the best speedometer recalibration tool. I have looked at the rough country and the superchip version. There’s $100 difference in price. Anyone used the superchip? Any issue with the rough country tool?

How did you check your speed against the newly recalibrated speed?

AlphaOBD... very easy if you watch the video and become familiar with the tool. $50. $25 for a bluetooth OBD2 connector and $25 for the security module. Not to mention all the other functions you get with alfaOBd and the OBD2 can be used on other cars with freeware too.

Superchips looks nicer and has the ability to tune if you unlock your computer, but it appears the Rough Country does the trick for tires if that's what you're looking for. I've been looking at Alpha ODB, but not sure if I want to go down that spiral. Was also considering the stealership as I only really need the speedo recalibrated, depending on what they charge I'll probably end up with Rough Country

My dealership quoted me a price of $100 to recalibrate. So a few dollars more and I have the tool

Buy the Rough Country. It works and its inexpensive. I tried the new Hypertech and had to return it.

First post, I've been lurking since I bought my '21 Limited two weeks ago. I already leveled mine and put bigger tires on it (it's at the shop getting an alignment right now). I called my dealership about recalibrating the speedo. They said they use FlashCal, which I had researched but found that it's only compatible with the '19s and '20s. The service writer told me they've used it on 9 or 10 '21s so far and it works. My Flashcal is supposed to show up today. I'll reply back after I test it out, but given the dealer was willing to do the recalibration with the Flashcal for me, I'm assuming it should be good to go.

Here's the link:

Really easy to do and my speedo is spot on with the GPS on my phone now. Make sure you measure the actual height of your tires, not the stated height on the tire documentation, they compress a bit under the weight of the truck. My tire's stated height vs. measure height was 3/4" different.

I would assume (hopefully) that if the flashcal is listed as working for the 19’s and 20’s but also works on the 21’s than the RC unit should be the same. I’m going to go ahead and order and and give it a go whenever my truck actually shows up.
My dealer recalibrate mine I had to buy a fca package for $125 and hr of tech time.

That's interesting, my dealer told me that Ram does not provide them access to the software like Jeep does, they have to use a calibration tool and my dealer uses the Superchip Flashcal to do it. They said they could take my VIN and order it and then provide the calibration service. I cut out the middle man, ordered it myself (I'm sure for less money than they'd charge me) and then took 15 minutes to program it myself. I'm sure there are people who are more comfortable letting the dealer do it so if it's screwed up, it's on the dealer. I was willing to take the risk and if I screwed up I'd have to pay on the dealer on the backend to fix it. Thankfully it turned out good for me.

I am surprised they charged a FULL hour of tech time for a 10-15 minute job
I guess they think none of us know any better.....

Bought the RC speedo calibrator worked great , shift points work better I think ,it seems to stay in gear longer as you accelerate , but even before calibration the 8 SPD with 37 inch tires shifted pretty good, the tool can also read codes and clear them, so not a total loss, still will be a useful tool for 140 bucks,
