Review on Increase Fuel Efficiency, Save Gas, and Boost Horsepower with the Innovative Performance Chip/Power Programmer for Toyota Tundra 3.4L, 4.0L, 4.6L, 4.7L, and 5.7L by Mayrando Clark

Revainrating 5 out of 5

Pretty good at spare parts

When it arrived it didn't have Toyota truck installation instructions. I was able to find what I needed online. The chip itself works well and I've noticed a decent improvement in economy and performance.

Pros
  • Certified
