This kit includes everything needed to delete AFM/DOD (Active Fuel Management) for GM Gen IV 5.3L engines, with VVT or Non-VVT camshaft options selectable at checkout. Unlike performance-oriented DOD delete kits, this version uses a TSP/GM single bolt stock-style camshaft for a more factory-like driving experience while still eliminating the reliability concerns of AFM/DOD.
⚠️ Important Note: Tuning is required after installation. A custom tune or the optional TSP/Diablosport handheld tuner (TSP-TS-3000) is necessary to ensure proper engine performance.

Frequently Asked Questions:
Q: Do I need to select VVT or Non-VVT?
Yes. This kit is available in VVT and Non-VVT camshaft configurations — select the option matching your specific engine at checkout.
Q: Is tuning required after installing this kit?
Yes. A custom tune is required after installation. An optional TSP/Diablosport handheld tuner (TSP-TS-3000) is available to add at checkout.

Yes. A 12-count set of stainless steel header bolts for LS/LT applications is included.
