Tuners, Programmers & Performance Chips
Unlock your Toyota's hidden performance with tuners, programmers, and performance monitors. These electronic upgrades can optimize shift points, adjust throttle sensitivity, recalibrate for larger tires, and monitor real-time engine data — all without opening the hood.
Performance programmers are especially useful after modifications like intake upgrades, exhaust systems, or tire size changes that benefit from recalibration.
Frequently Asked Questions
Do I need a tuner after installing larger tires?
Yes, recalibrating your speedometer and odometer after a tire size change is important for accurate readings and proper transmission shift points. Most programmers can adjust the tire size calibration in minutes.
Will a tuner void my warranty?
Dealers can detect tuner use via the ECU flash counter. While a tune itself does not automatically void your entire warranty, the dealer may deny specific powertrain claims if they determine the tune contributed to the failure. Some tuners offer a warranty-friendly stock restore mode.
