Frequently Asked Questions
Will a performance chip really improve my gas mileage?
Some chips offer an economy mode that optimizes your air-fuel ratio for better efficiency during highway driving. However, if you use the extra power for aggressive acceleration, your fuel consumption will likely increase rather than decrease.
How difficult is the installation process?
Plug-and-play modules are quite simple and usually involve connecting a few wiring harnesses to existing sensors. Handheld tuners require you to plug into the OBD-II port under your dash and follow the on-screen prompts to download the new software.
Can I switch between different performance levels?
Yes, most reputable handheld programmers allow you to store multiple tune files on the device. You can swap between a towing tune, a daily driving tune, and a maximum power tune whenever your needs change.
Does a performance chip affect my truck's towing capacity?
A good tune can make towing feel much easier by increasing low-end torque and smoothing out transmission shift points. Just remember that you cannot physically change the manufacturer's tow rating, so stay within the safe limits of your Sierra's chassis.
Should I upgrade my exhaust or intake at the same time?
Adding an intake or exhaust system allows your engine to breathe better, which lets the chip maximize power gains. While you do not have to upgrade these parts, doing so helps the engine make the most of the new software settings.
