The AFE Power 77-43026 is a vehicle-specific aFe Scorcher tuning module designed to plug directly into your engine's sensor harness and optimize ECU parameters for maximum power. This performance chip targets late-model applications with precision calibration, delivering noticeable horsepower and torque improvements without a permanent reflash. It reads MAF, MAP, and boost pressure signals and adjusts them in real time for optimal combustion efficiency.

This tuner offers multiple power levels — Economy for fuel savings, Towing for low-end muscle, and Performance for maximum output — switchable on the fly. The 77-43026 module uses a weather-resistant housing and direct-connect harness that requires no cutting or splicing. Gains vary by fuel type and vehicle configuration, with diesel applications typically seeing the largest improvements.

Installation is plug-and-play: locate your vehicle's MAP/MAF sensor connector, unplug it, insert the Scorcher harness inline, and mount the module. Average install time is under 20 minutes. The kit includes the main module, vehicle-specific T-harness, wireless remote, and mounting hardware. To return to stock, simply remove the harness and reconnect the factory sensor — no programming or ECU flash required. aFe Power provides full warranty coverage.

For a vehicle-specific tuning solution that delivers real, repeatable power gains with zero permanent changes, the AFE Power 77-43026 is the right choice. Add it to your cart and experience the difference aFe Scorcher engineering makes.

Frequently Asked Questions

How much horsepower will this aFe Power performance module add to my vehicle?

The AFE Power 77-43026 is capable of adding up to 35 horsepower and 40 lb-ft of torque on most applications without any other modifications. These gains come from optimized fuel and ignition timing maps that work with your existing engine sensor signals to deliver more power safely. The Scorcher platform is known for providing clean, linear power delivery that feels just like a factory performance upgrade right out of the box.

Can I install this aFe Power performance module myself or do I need a mechanic?

Installation of the AFE Power 77-43026 takes about 20 to 30 minutes using basic hand tools, and you can absolutely do it yourself in your driveway. The module connects inline with your MAF sensor and boost pressure sensor using weather-sealed plug-and-play harnesses that clip right into factory connectors. No laptop, tuning software, or professional mechanic skills are required to get this module up and running on your vehicle.

Will this aFe Power performance module void my factory warranty or leave any traces?

The AFE Power 77-43026 is designed to be completely reversible and leaves no permanent trace on your vehicle's ECU memory or flash counters. You can remove the module in just a few minutes before any dealer visit, returning your truck or SUV to its completely stock programming. Under federal law, a dealer must prove the module caused a specific failure before they can deny a warranty claim against you.

Does this aFe Power performance module work with both gas and diesel engines?

The AFE Power 77-43026 is available in separate configurations specifically tailored for either gas or diesel engines, never both. Gas versions focus on air-fuel ratio and ignition timing optimization, while diesel versions optimize fuel pressure and turbo boost curves for best results. You must select the variant that matches your engine type to get proper performance gains and ensure safe, reliable operation on your vehicle.

What fuel economy gains can I expect from this aFe Power performance module?

Many drivers report gaining between 1 and 3 MPG after installing the AFE Power 77-43026, especially during highway cruising conditions. The optimized air-fuel ratio and timing curves allow your engine to operate more efficiently under light to moderate throttle applications. Your actual results will depend on your driving habits, vehicle condition, and whether you can resist using that extra horsepower once you feel the difference.

Will this aFe Power performance module work safely on my completely stock vehicle?

Yes, the AFE Power 77-43026 is carefully calibrated to work safely on completely stock vehicles with zero additional modifications required. The tuning parameters stay well within factory safety margins for fuel trims, ignition timing, and boost levels across all driving conditions. If you add cold air intakes, exhaust systems, or other upgrades later, the module will continue to complement those modifications nicely for even more power.
