Hello everyone !
From a person that just reads these posts normally and never posts I wanted to post my experience.
I have a 2015 Tahoe LTZ and bought the full kit (front and rear) from X-ineering. After sometime (out of the warranty) I started to get the suspension warning on my dash. I bought the software and cable from X-ineering to dig into into it deeper and found that I had one sensor open. Instead of purchasing a new half kit for $250 I decided to go a different route.
If you have already bought the full kit and want to DYI repair this kit yourself this is what I did. I put the sensor into boiling water on the stove for 10 min to warm it up enough to chip away at the 2-part epoxy they use to incase the resistor. Once the resistor is exposed and with a pick or the proper tool pull the resistor out of the connector and replace it. It will cause you to heat the solder up to remove and swap out the resistors on the terminals. Then put it all back together and do you best to seal it back up the best you can.
Here is the link to the resistor that I used.

X-ineering sells a good product, the time and effort they put in to make this whole set up look factory is why its expensive. But if you have some skills and want to try going around it there you go. I didn't want to the first time because figuring out where to start was above my head.
Thanks
