The Forester XT is the sleeper in the Subaru lineup, and the EJ255 responds to proper tuning the same way any boxer turbo does.
The 2007 Subaru Forester XT EJ255 runs a boxer engine with genuine tuning potential, and the factory ECU is the limiting factor in reaching it. The Tuned By Shawn Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
Advantages
- Boost delivery that's precise and repeatable instead of factory ECU conservative
- Throttle response that's direct and proportional to your inputs
- Flat-four character that comes through clearly when the tune is built for the actual engine
- Fueling that stays accurate at temperature, not chasing a moving target
- A tune that reflects your modifications instead of compensating for them

The Details
Built specifically for this vehicle's connector layout with OEM-spec connectors and correct wire gauge throughout. Your factory harness stays completely untouched and the car can return to stock at any time.
