Recalibrate for larger than stock wheels and tires

[S33k3r]

HP Tuners is a great tool to have. The hundred dollar license fee for every additional vehicle sucks, but at the end of the day I've found it to be worth it both for speedometer correction and to adjust transmission tuning to help with longevity.

Very surprised that tuner didn't have any sizes to choose from that were 33".

I have also found that most of my vehicles I have done corrections on, when calibrated to GPS speed, have liked to be set to a tire diameter around half an inch smaller than the true size.

Thanks for the recommendation. What is the actual price of HP Tuners? I've looked at it, and I can't tell. FYI, I have at least 4 of these things I am going to be caring for...

Last time I bought a module, it was $300 for the device plus a $100 license for each vehicle you unlock. The license is tied to the vin and the module, so keep up your module. If you lose it you'll have to re-purchase your licenses.

The current price for the MPVI3 is $399 and it takes the universal credits versus the GM, Ford or Dodge specialized credits. Also some of the third party resellers offer a small discount on purchasing the credits.

One other thing to note is not every vehicle will take just two credits to license. Many of the newer, think 2014 and up, require up to 4 credits and some even require an unlock service.

Will any of these tuners work on a”97” Tahoe speedometer ?.
