Range Technology AFM-DFM DISABLER,Blue,Compatible with V6 & V8 GM - $75

condition: like new
make / manufacturer: HOLLEY PERFORMANCE PRODUCTS
model name / number: RET-RA003B
The Range AFM/DFM Disabler allows your V6 or V8 GM vehicle to run in full cylinder mode at all times, preventing the Active or Dynamic Fuel Management system from dropping cylinders.

Used in our 14 Chevy Suburban with the 5.3 - works like a charm. (Suburban for sale too) Stops dropping into V4 mode and run on all 8 cylinders all the time, and the transmission shifting is got smoother. (aka stops the Cylinder deactivation via Dynamic Fuel Management)
