What is a Performance Chip? Do Performance Chips Work?

Performance chips are a type of electronic device that works with your Tundra’s onboard computer. Once installed, the chip adjusts and boosts the effects of a turbocharger (if the vehicle has one), air-to-fuel ratios, and vehicle timing. The result is a truck with increased performance in a variety of circumstances and situations.

Depending on the quality of the performance chip, these devices have been proven to boost a vehicle’s power by anywhere from 25 to 75 horsepower on average. For a Tundra, this can mean a 10% to 30% improvement over the stock vehicle. Keep in mind that the effects of these chips can be more noticeable on certain trims of the Tundra than others.


How Do Performance Chips Work?

Every Tundra—and every vehicle for that matter—has a factory chip installed. Also known as a performance tuner or engine control unit, this chip accesses the vehicle’s computer or engine control module through a lookup table. Based on a manufacturer’s specifications, this lookup table dictates how an engine responds to different inputs such as how much power to provide during aggressive acceleration.

A performance chip changes these parameters to provide more impactful and powerful driving by increasing torque and horsepower, changing when the vehicle shifts gears and tweaking the timing of the ignition. In addition, some chips can also get better fuel economy by limiting the fuel-to-air ratio when coasting or on cruise control.

Why Did These Tundra Tuners Make Our List? 

Every chip comes with a different blend of characteristics to accommodate different types of driving styles, tastes, and budgets. So when you’re searching for a performance chip, you want to make sure that it has all the features you require. In this list, we searched for tuners with various attributes that drivers crave. Here are some of the top reasons for their inclusion.

Fuel Economy Improvement

Just because a performance tuner improves your Tundra’s performance doesn’t necessarily mean that it wreaks havoc on your fuel economy. In most cases, it’s much to the contrary. Many of these chips have parameters that can do both. The bottom line is that you’ll save money at the pump, even with an uptick in overall performance.


Air-to-Fuel Ratio

Combustion engines in a gas-powered Tundra rely on a mix of air and fuel to power the vehicle. Ignited by a spark plug, this is what makes your engine run. However, many manufacturers—including Toyota—have limits on this air-fuel mix to meet various government regulations. But a performance chip alters these parameters in the computer, which tells fuel injectors to change how much fuel to use. The result is better performance in all gears and RPMs.

Ignition Timing

Furthermore, the air-to-fuel ratio is also greatly affected by ignition timing. When the timing is on, the power of your Tundra increases. When it’s off by even a fraction of a second, it decreases. By installing a performance chip, your truck gets the optimal spark it needs for enhanced performance.

Review of the Best Performance Chips For Toyota Tundra

Because performance chips don’t require a huge budget or DIY mechanic skills, they’re ideal for all types of Tundra owners. So whether you want a tuner that increases your fuel economy, a chip that turns your truck into a performance powerhouse, or something in between, you’ll find it in these reviews of the best performance chips for the Toyota Tundra.
