Review on π Enhance Fuel Efficiency & Boost Power: Performance Chip/Power Programmer for Ford Expedition 3.5L, 4.6L, and 5.4L Engines by Kevin Grizzle
I didn't feel the difference
After almost 20 hours of checking my connections and disconnecting my car's battery. I didn't feel any difference in performance. The main thing I was looking for was an improvement in throttle response, but it appears to be exactly the same as before the install.
Pros
- Price
Cons
- Little things
