JMS Control Modules

JMS Chip & Performance: Street-Legal Power, Plug-and-Play Simple

Founded in 1993 and headquartered in DeBary, Florida, JMS Chip & Performance has built a reputation as a specialist in street-legal electronic performance upgrades. Rather than requiring ECU reflashes or invasive engine modifications, JMS engineers its products around a core philosophy: deliver real, measurable performance gains through intelligent, plug-and-play electronic modules that work seamlessly with your factory wiring and sensors.

Every JMS product is proudly designed and assembled in the USA, and the brand backs its lineup with a lifetime warranty — a level of confidence that speaks directly to the quality of their engineering.

The PedalMAX: Throttle Response Reimagined

The crown jewel of the JMS lineup is the PedalMAX Accelerator Pedal Boost Module. Modern drive-by-wire vehicles introduce a programmed delay between pedal input and engine response — a compromise that can make daily driving feel sluggish and towing feel unresponsive. PedalMAX plugs directly in-line between the accelerator pedal position sensor and the vehicle harness, allowing drivers to tune throttle sensitivity on the fly without touching the ECU. Whether you're crawling through traffic or pulling a trailer uphill, PedalMAX puts throttle control back in the driver's hands.

BoostMAX: More Power from Your Turbocharged Engine

For drivers running turbocharged engines — especially Ford EcoBoost platforms — the BoostMAX Turbocharger Electronic Boost Controller is a natural complement to PedalMAX. BoostMAX connects to the factory MAP and TIP sensors using OEM-style connectors, delivering on-demand increases in low-end, mid-range, and top-end power and torque. The included remote boost adjustment knob lets you dial in your exact boost enhancement setting, and the two modules can even be stacked together for compounded gains across both throttle response and turbo output.

TractionMAX: Grip When You Need It Most

High-horsepower and forced-induction vehicles often struggle to put power down cleanly, especially from a standing start. The TractionMAX Traction Control Module was built specifically for traction-limited vehicles, using dual adjustment dials to let drivers manage both pedal feel and the available traction envelope — all adjustable on the fly. Units are fully waterproof and compatible with both factory and aftermarket tuning setups.

FuelMAX: Squeeze More From Your Factory Fuel Pump

When power levels climb, fuel delivery becomes the limiting factor. The FuelMAX Electric Fuel Pump voltage booster uses proprietary digital technology to increase fuel delivery from your existing OEM pump by up to 85% — supporting builds up to 1,000 horsepower on a single pump and up to 1,350 horsepower with dual stock pumps. No dropping the fuel tank, no expensive pump replacement — just a clean, splice-in installation that gets your factory hardware performing at a much higher level.
