Speedometer calibrators Hypertech or Rough Country

[dieselfan1]

I'm going to need one of these. I'm going to 37" tires and my speedometer will be off by 10 mph @ 70. Not sure if the Hypertech is worth the extra $90. It seems they both do the same thing.

Anybody ever use one of these?

Is it complicated?

Thanks guys.

I have the hypertech.  Love it.  Got it for $208 from autoanything after asking for a discount.  The rough country probably works the exact same.  I chose hypertech because it's what my dealer uses on their lifted trucks and I have a warranty.

I have a Hypertech did this before I got tuned. This is also what my local Chevy dealer uses on the trucks/suvs they do. Very simple to operate. Also works if you do a gear swap the Rough County doesn’t specify if it does or not? If that’s something you might do down the road?
 

I’m usually all about buying new stuff for my vehicles but this is one of the few things where if I do it again on another one I’d probably buy a used unlocked one or a refurbished unit since it’s literally something you’ll use once or twice anyway. Most handheld tuners will also have this feature so even if you don’t use any of the “tunes” if you find a new/used/referb cheaper it will get the job done & be more desirable to someone else if you sell it someday. Just make sure if you go used it’s unlocked.
 

Autoanything.com has a low price guarantee that if you find it cheaper the will beat it buy a whole dollar. OH BOY I know but they also guarantee the price for a year so if you get one from them and come Black Friday when these are on sale everywhere they would refund the difference. I did this with my tonneau cover Truxedo had it cheaper but no free shipping got Autoanything to price match with free shipping.

i bought the hypetech recalibrator and it worked perfect.  i put on 35" tires and my issue (other than the speedo being out) was pretty much every time i did a hard left turn the stabili-track system kicked in (sooooooo annoying!).

 

it was super simple to do - it just plugs into the truck, follow the prompts, enter your wheel height and wait while it does the install/update.
