Which one? Looking for the product that will bring me closest to stock function.

Went from 275/55/20 to 275/65/20...

 

anyone....? I was about to post the same question.

 

I have the Hypertech. RC did not offer one when I purchased the Hypertech.

The Hypertech works as advertised.

They appear to be very similar looking. The Hypertech costs more but has a lifetime warranty and can be upgraded to their tuner.

I'm pretty sure the RC does the same basic job at a cheaper price.

Why do either? Buy a good OBD dongle and recalibrate with Forscan. Not only do you fix your problem for less money, but you get a substantial diagnostic tool as well.

 

I own neither but used ForScan to calibrate. $30 OBD reader and laptop I have, free ForScan program and license, a few minutes time. Got my speedo within .5MPH compared to 3 different GPS units at 55MPH. KM
