Computer chip programmers might just be the best power-per-dollar investment for your car or truck. CPU programmers boost power and fuel efficiency using a variety of low and higher octane fuel levels. But the extent of CPU programmers don't end there. Some even recalibrate your speedometer when using larger diameter tires. Or scan the engine for trouble codes.
Chip programmers work by altering factory fuel/ignition timing tables in the Electronic Control Module (CPU). A lot of today's chip programmers also provide you with the ability to switch to different performance modes, such as:
- improved torque
- more horsepower
- improved fuel efficiency
And although max power is often intended to be gained using high-octane fuel (91), some programmers give your ride significant upgrades even with lower octane fuel (87).
Computer chip programmers are usually easy-enough to install but often vary on software updates. Nowadays most manufacturers make software updates available for download on their websites.
So... are you ready to make your baby purr? There really is no downside. CPU programmers give you performance, power and fuel economy -- a seeming contradiction -- all in one product. Computer chip programmers provide as much as 15-30 extra horsepower and 30-50 pounds-feet of torque (with 91 octane fuel), and, depending on the settings, you can also improve your vehicle's fuel economy by as much as 20 percent (highway miles).
