About EFI Live Duramax
The Duramax engine, which provides both Chevy and GMC trucks with unbridled power, can deliver even more load-dominating performance with some slight tweaks. For those interested in such an upgrade, the series of EFI Live Duramax tuners can provide the extra punch you desire. Engine tuners function primarily by manipulating the onboard computer in order to deliver more fuel or air to the ignition, just when you need it. In essence, they reprogram your truck to respond like you imagine a diesel should, but the factory settings are limited in the name of fuel efficiency. In reality, an EFI Live Duramax tuner, such as the AutoCal, can actually increase your fuel efficiency. The AutoCal comes with five presets designed for different situations. The towing setting, which increases the truck's power output by 30 HP, is the most popular for everyday situations. The other settings are only approved for race track use, but they can increase performance by a mind-blowing 140 horsepower. That's an astonishing gain for a simple computer upgrade. A number of EFI Live tuners can be found for sale on eBay.
