Performance Chips, Power Programmers & Tuners FAQ

Question 1

What are performance chips, power programmers, and tuners?

Accepted Answer

These devices or calibrations may alter certain engine or transmission control settings, monitor vehicle data, or provide diagnostic functions. Their features and compatibility vary by product and vehicle.

Question 2

How do I select a compatible tuner?

Accepted Answer

Confirm the vehicle year, make, model, engine, transmission, drivetrain, emissions configuration, and any existing modifications. Use only products specifically listed as compatible with the application.

Question 3

Will a tuner increase horsepower, torque, or fuel economy?

Accepted Answer

Results vary by vehicle, calibration, fuel quality, operating conditions, and supporting modifications. Do not assume a specific gain without verified product- and vehicle-specific information.

Question 4

Can a tuner affect emissions compliance?

Accepted Answer

Yes. A calibration that changes emissions-related operation or disables, removes, or bypasses required emissions equipment may not be permitted for street use. Follow applicable laws and product instructions.

Question 5

Can tuning affect a vehicle warranty?

Accepted Answer

Modifications may affect warranty coverage or claims, depending on the vehicle, warranty terms, and the relationship of the modification to a failure. Review the applicable warranty information before installation.

Question 6

Do I need a different tune after installing performance parts?

Accepted Answer

Some modifications may require a compatible calibration for proper engine operation. The correct approach depends on the specific vehicle and components; an unsuitable tune can cause drivability, reliability, or emissions-related issues.

Question 7

Can a tuner be used on more than one vehicle?

Accepted Answer

Device licensing, vehicle pairing, and transfer policies vary by product. Check the manufacturer’s instructions before attempting to use a device on another vehicle.

Question 8

Should I use premium fuel with a performance tune?

Accepted Answer

Use the fuel grade specified by the tune provider and vehicle manufacturer. Using fuel below the required octane rating can contribute to knock, reduced performance, or engine damage.

Question 9

Can a tuner diagnose a check-engine light?

Accepted Answer

Some devices can read and clear diagnostic trouble codes, but clearing a code does not repair the underlying fault. Diagnose and correct the cause before clearing codes or continuing to drive.

Question 10

What should I do before programming a vehicle?

Accepted Answer

Follow the product instructions exactly. Use a stable, adequately charged battery, verify vehicle compatibility, avoid interrupting the programming process, and retain the original calibration when the product allows it.
