Review on Advanced Performance Chip/Power Programmer for Land Rover Discovery & Discovery Sport 2.0L, 3.0L, 3.9L, 4.0L, and 4.6L - Enhance Fuel Efficiency, Save Gasoline & Boost MPG, Elevate Horsepower & Torque! by Joseph Hernandez
DOES NOT WORK AS RECOMMENDED!
Installed exactly as instructed. Left the battery unplugged for a full day as instructed. Installed the part and my Discovery 2 ran fine but the mileage was cut almost in half. Smelled gas in the exhaust, picked it up before my catalytic converters were destroyed.
- Great design
- Hard to tell
