Legacy SS - Stage 1 Performance Chip

Our Stage 1 chip was carefully developed to maximize the potential of a stock or lightly modded Legacy Turbo. You will feel your Legacy come alive with a significant increase in mid-range torque (up to 17%) as well as a noticeable gain in high RPM power (up to 22%). If you can stay out of the boost, you should also see a 5-8% improvement in fuel economy.

*NEW* For users with access to a Select Monitor Cable, our free REVScan software can be used to adjust fuel ratio under full throttle to consistently deliver maximum power.

At 13 psi of boost, this is the most power the stock MAF sensor and fuel injectors can handle. You will also notice the turbo spooling up quicker at part throttle resulting in smoother power delivery.

If your Legacy is still stock but you are planning on later bolt-on upgrades, this chip will still work for you (see manual for details).
 

Required Upgrades:

• None (Stock)

Optional Upgrades:

• Catback exhaust - 2.5" or larger
• High flow downpipe - 2.5" or larger
• Modified factory air intake (resonator and snorkel delete)
   

Optimized for Power

Through extensive testing, we have determined the best settings for both power and reliability. We remapped the factory boost control to optimize turbocharger operation. Fuel and spark timing maps are also fine-tuned to deliver better performance while preventing knock and maintaining safe exhaust gas temperatures.
 

Factory Reliability

We retained all the built-in factory safety features to protect your engine from dangerous operating conditions such as poor quality fuel or faulty sensors. The overboost fuel cut feature is retained but set to a higher threshold.
 

Simple Plug-In Installation

Using our specially developed chip adapter board, installation is simple. You do not need to be mechanically inclined and no special tools are necessary, just a wrench and screwdriver. No soldering is required.
 

Adjustable

Each chip is programmed with two calibrations (Normal and Power mode), which can be selected by changing a jumper switch on the adapter board. Normal mode is tuned for 91 octane while Power mode is tuned for 93 octane.

An external switch is provided to allow switching from the driver's seat.
