Review on π Increase Fuel Efficiency, Enhance Power: Innovative Performance Chip + Power Programmer for Ford F-250, F-350, F-450 & F-550 4.6L-7.5L Engines by Paul Lee
Nothing has changed. I followed the instructions, however.
Nothing has changed. I followed the directions, but my truck's fuel economy stayed the same. And I don't notice any difference in performance.
Pros
- DOES NOT make permanent changes to your car's computer! This does not invalidate your factory warranty and no exhaust systems are changed. The performance chip is fully compatible with your Ford F-250, F-350, F-450 and F-550 Super Duty on all trim levels including 4.6L, 4.9L, 5.0L, 5.4L, 5 .8L, 6.2L, 6.8L and 7.5L engines.
Cons
- There are other interesting options.
