At Amazon, this AFM/DFM Disabler for GM V6 & V8 Engines for $66. It's the best price we could find by $2. It plugs into the OBD-II port and leaves the factory ECU programming unchanged, so unplugging it returns the vehicle to stock settings. Compatibility varies by model, and the listing notes it does not fit 10-speed transmission models or 2022+ refresh models. Shipping is free. Buy Now at Amazon
