Bigger, better, faster and it will make you better looking! We’ve heard a lot of promises and claims in our time, and most of them we go by without the slightest temptation. But when MSD launched its Atomic EFI, claiming to make electronic fuel injection (EFI) conversion easy and fast, it got our attention.
In the past couple of years, there have been a few EFI systems introduced that promised easy installation and laptop-free tuning. In fact, they claim to be self-tuning. These are throttle-body based systems, bolting on in place of a four-barrel carburetor. They don’t have to control the ignition system. And they don’t require a degree in air/fuel ratio technology to tune. All of that sounded too good to be true, so we decided to put one of them to the test.
