That is a 07 Silverado classic, not a Tahoe. 07 Tahoe is going to be an E38 ECM CAN bus vehicle. OP does your JET cable support CAN bus? I know the original Tunercat didn't and you had to buy the updated CAN bus TC cable to do those vehicles.

Edit - Just checked Jet's web site. That Jet tuner is like the original Tunercat and is only for pre-CAN vehicles.

The only way Tunercat will sell you the updated cable is if you were an original TC cable purchaser before they sold the product to Jet. I don't know if Jet sells an updated CAN bus cable.

If JET doesn't do serial number matching or anything like that, all you need is a device that can handle CAN signals. OBDX Pro carries just such a device, but unfortunately the cheaper version isn't available at the moment. So if you absolutely need it now, you'd have to jump for the more expensive one: https://obdxpro.com/product/obdx-pro-gt-obd2-diagnostics-and-tuning

The cheaper one is here, if you don't mind waiting: https://obdxpro.com/product/obdx-pro-vx-obd2-diagnostics-and-tuning
