I'm not exactly sure if this thing works. I have .

I'm not entirely sure if this thing works. I have a 2016 Tundra, 5.7V-8. I'm not a kid, I don't jump on the gas pedal. Before installing, I was getting 12-12.5 mpg. My mileage is now 12.2. It's all city driving. I don't feel much power bragging either. Since I haven't raced on the road, I'll just say it's ok.

Pros
  • Price
Cons
  • Very expensive
