JET Performance's JET Performance 38613C JET Stage 1 Computer Chips/Modules is a Stage 1 tuning solution that upgrades your vehicle's ECU calibration for better throttle response and increased output. This performance chip or module replaces the factory programming with JET's optimized fuel and spark maps. It's engineered for daily-driven vehicles where reliability and drivability matter as much as peak power. This unit is JET part number 38613.

The JET Stage 1 typically delivers 15-25 HP and 20-30 lb-ft of torque gains on stock or mildly modified engines. Calibration modifications include optimized air/fuel ratios, revised ignition timing curves, and adjusted transmission shift points on automatic-equipped vehicles. The Stage 1 is designed to work with factory components and does not require any supporting modifications.

JET provides vehicle-specific installation instructions with every Stage 1 unit. Chip-type applications require ECU removal and EPROM replacement; module-type applications plug inline or into the diagnostic port. No tuning software or laptop is required. The original factory calibration can be restored at any time by reversing the installation process.

JET Performance has been tuning vehicles since the 1980s, and this Stage 1 chip/module continues that legacy. Add JET Performance 38613C JET Stage 1 Computer Chips/Modules to your build and enjoy professional-grade ECU calibration without a custom dyno session.

Frequently Asked Questions

How much power will this JET Stage 1 computer chip add to my daily driver?

The JET Performance 38613C JET Stage 1 Computer Chips/Modul delivers 15 to 25 horsepower and 20 to 30 lb-ft of torque on most applications with no other modifications required. JET Stage 1 tuning focuses on optimizing the factory calibration for improved throttle response, passing power, and overall drivability on the street. These gains are achieved without pushing any engine parameters beyond safe factory specifications, so reliability is not compromised.

Can I install this JET Stage 1 computer chip at home without special tools?

Installation of the JET Performance 38613C JET Stage 1 Computer Chips/Modul depends on whether you have the plug-in module style or the chip style replacement. Module-style units connect directly to your OBD-II diagnostic port or sensor harness in under 20 minutes with zero tools required. Chip-style units require opening the ECU case but come with clear, illustrated instructions that make the swap straightforward for any DIY owner.

Will this JET Stage 1 computer chip be visible during dealer service visits?

The JET Performance 38613C JET Stage 1 Computer Chips/Modul is engineered to be completely undetectable once installed because JET uses the factory ECU's own programming protocols for their calibrations. Module versions can be unplugged and removed in just seconds before any dealer visit, leaving absolutely no trace of modified tuning. Chip versions require swapping back to the factory PROM, a simple 15-minute process that restores everything to stock.

Does this JET Stage 1 computer chip work with both gas and diesel trucks?

JET offers the JET Performance 38613C JET Stage 1 Computer Chips/Modul in separate configurations for both gas and diesel engines, each calibrated specifically for that fuel type. Gas calibrations optimize ignition timing and fuel curves for maximum safe power on pump gasoline. Diesel versions adjust injection timing and fuel pressure to improve low-end torque and throttle response, so be sure to select the correct version for your vehicle.

Will this JET Stage 1 computer chip improve my fuel economy during normal driving?

Most owners see a modest 1 to 2 MPG improvement with the JET Performance 38613C JET Stage 1 Computer Chips/Modul thanks to optimized part-throttle fueling strategies that reduce wasted fuel. JET's Stage 1 calibration smooths out the overly rich or conservative areas found in many factory tunes for better everyday efficiency. The key to realizing fuel economy benefits is maintaining light to moderate throttle habits during your daily commute.

Will this JET Stage 1 computer chip work on my vehicle if it is stock?

The JET Performance 38613C JET Stage 1 Computer Chips/Modul is designed as a safe first performance upgrade for completely stock vehicles with factory intake, exhaust, and engine components. JET Stage 1 calibrations are extensively tested on stock hardware to ensure reliable operation and smooth drivability across all conditions. The chip or module will continue to perform well and can adapt if you add aftermarket intake or exhaust upgrades later down the road.
