The Six-Gun Diesel Tuner and Speed-Loader for Ford 6.0L Power Stroke engines is a quick and easy plug-and-play power mod. The six-level control knob is the only part that's exposed in the cockpit. The speed loader module is small but offers big increases in power. It's tuned to produce 23 hp and 25 lb-ft and comes with a high-quality temperature probe to give you temperature-limiting control that safeguards your engine by limiting fuel delivery as exhaust-gas temperature increases.
