How much should I budget for a full AFM/DOD delete on my GM truck?

A complete AFM delete typically runs between $3,500 and $6,000 depending on whether we're doing lifters only or a full cam-and-lifter swap. The job includes non-AFM lifters, a DOD delete kit, new valley cover, and a custom tune to disable the cylinder deactivation in the ECU. David Jr. handles the tuning in-house to make sure the engine runs clean through Arizona emissions.

What does an AFM/DOD delete involve?

The AFM lifters are replaced with standard non-AFM lifters, the AFM valve lifter oil manifold (VLOM) is either replaced or deleted, and the ECU is reprogrammed to eliminate the cylinder deactivation logic. David Jr. also typically installs a DOD delete plug kit.

Will an AFM delete affect my emissions compliance?

In Arizona, this is an important consideration. The AFM delete changes the emissions calibration, which could be an issue during testing. David Jr. can walk you through the implications for your specific vehicle and registration situation before you decide.

GM AFM/DOD Service — Path 2 (Performance Delete)

A permanent fix for out-of-warranty GM engines. We perform full mechanical AFM/DOD deletes using high-quality BTR, TSP and Summit Racing performance components. Note: This path prioritizes performance over factory warranty. By appointment only. Tuning by Black Bear Performance. Call to book.

Apex Automotive in Gilbert, AZ, offers a specialized GM AFM/DOD Service — Path 2 (Performance Delete) — designed for out-of-warranty GM engines seeking a permanent solution to Active Fuel Management (AFM) and Displacement on Demand (DOD) failures. The AFM/DOD system, common on GM’s 5.3L, 6.0L, and 6.2L LS and LT engines, improves fuel economy by deactivating cylinders under light load. However, lifter and camshaft failures are prevalent, especially in Arizona’s harsh desert climate where extreme heat accelerates oil degradation and mechanical wear. When AFM components fail out of warranty, a full mechanical delete eliminates the AFM system entirely, replacing it with high-quality performance components from trusted brands like BTR, TSP, and Summit Racing. David Jr. leads this process with a diagnostic-first approach, thoroughly confirming the extent of AFM damage through OBD-II scans and live data analysis before recommending the delete. This ensures that the delete is necessary and tailored to your engine’s condition. The performance delete involves replacing AFM lifters with solid mechanical lifters, installing a compatible camshaft, and reprogramming the engine control unit with Black Bear Performance tuning to optimize power and drivability. This upgrade not only removes the risk of future AFM-related failures but also enhances engine responsiveness and reliability, a benefit for drivers facing Gilbert’s high temperatures and demanding driving conditions. It is important to note that this path prioritizes performance and durability over factory warranty protection. The installation is meticulous, adhering to exact torque specs and assembly procedures to ensure long-term durability. Our by-appointment-only service guarantees your vehicle receives dedicated attention from David Jr., your personal mechanic. If your GM engine suffers from AFM lifter failures or you desire improved performance and peace of mind, trust Apex Automotive to deliver a professional, high-quality AFM/DOD delete tailored to East Valley’s desert demands.
