No — a throttle controller does not add horsepower. It changes how quickly pedal position translates to throttle-body opening, so the truck feels more responsive without making more power. For actual output gains you need a tuner, intake, or exhaust. What it does fix is the artificial off-idle lag many drive-by-wire trucks carry from the factory.

Yes, but use the low-sensitivity mode, not the aggressive one. On the trail you want fine, predictable pedal control for crawling over obstacles, and most controllers include an off-road or eco setting that softens tip-in for exactly that. High-sensitivity modes are better suited to on-ramps and passing. Being able to switch modes from the cab is the real value off-road.

No — most are plug-and-play at the accelerator pedal connector and install in 10 to 15 minutes with no cutting or splicing. The controller taps the factory pedal harness and mounts within the driver's reach. Filter by year, make, and model to confirm the correct plug for your vehicle. No tuning software or dealer programming is required.

You can, but most drivers don't. Aggressive modes make the pedal feel quicker off-idle, which is tiring in traffic and hurts low-speed modulation on ice or trails. Many owners run a middle setting daily and switch to eco for crawling or slick conditions. The modes don't change fuel-delivery limits, so there is no mechanical harm either way.
