These are what I used on my C5. Not sure if they work on the gmc. But it is a start. Without them the Corvette would go into limp mode and ruin your day.

Do a search...this was discussed many times. You can remove the "RTD" fuse from under the hood or resistor mod.

I just changed mine from oem to bilsteins in my 04 denali. Just disconnect your battery and then pull your RTD (#30) fuse, re-connect your battery and your good to go.
