Potluck
Optimize your fuel injection without the need for expensive dyno tuning. The RevTech DFO modifies the outgoing signal from the ECU to your injectors, increasing the duration of the spray of fuel and thereby richening the mixture. Adjustable pots allow you to add fuel where it is needed over three areas of the rev range. A fourth pot allows you to set a transition point from light-load cruise to high-fuel performance mode. This allows both basic tuning and more sophisticated fine-tuning for specific racing situations. The transition feature also has a load-sensitive function that overrides the base rpm setting to allow an earlier crossover whenever large throttle openings are introduced at low rpm.

Extremely Clean
Extreme EFI is now releasing its newest throttle-body and air-cleaner products to the public. These units are currently available in 50mm through 62mm throttle-body sizes, with intake-runner diameters of 1.660, 1.710, and 1.800 inches. They fit in the stock location and reuse the factory sensors to their full potential. They are CNC-machined in the USA and powdercoated with machined highlights to match the factory black or satin finishes.

Big Bore
The S&S single-bore induction allows riders of late-model Big Twins to build a big engine, supply all the fuel it needs, and still utilize other tuning systems they may have bought for their bike, such as the Harley-Davidson Screamin' Eagle Race Tuner for Delphi fuel injection, or many other aftermarket fuel controllers and replacement ECUs. The S&S single-bore throttle body has a throttle body that is 2-1/16 inches, so it has more than enough capability to supply a big engine. The single-bore tuned induction is available in chrome, wrinkle-black, or natural finish, along with both blue and red filter elements.
