Review on 🚀 Enhance Fuel Efficiency, Increase Horsepower, and Torque with our Innovative Performance Chip/Power Programmer for Toyota Sequoia 4.6L, 4.7L, and 5.7L Engines! by Kevin Parker

I've noticed an increase in horsepower, but that doesn't add up to petrol mpg. The only way to change the mpg is to say "drive conservatively" when setting it. Sure, if a person normally drives crazy and hits the gas, they're driving normally or conservatively. That person will see an increase in mpg. But if you drive with mpg most of the time and set that, nothing changes. I installed it for a month or more and nothing. The facility was crap too. There's a reason they don't show any electrical connections. It uses clips that simply pinch and cut through the vent sensor insulation. No vehicle-specific wiring harnesses or the like. As my car is Toyota I had to email about the wires as this is a universal installation guide and has nothing but a domestically made Ford Chevy GMC Dodge.
