These maps have been extensively tested on my personal vehicle and should be safe for use without a road tune. A margin of safety has been built in to them, and as such extra power can be gained from them through a dyno tune. They're intended for use on US cars only. All maps have been tested on 91 octane with up to 10% ethanol. For best results, BP-Amoco 93 octane is recommended.
Technical support is provided for up to 30 days after purchase. Your map and documentation will be delivered via email within 24 hours of payment.
You will need EcuFlash and a Tactrix cable to install these maps.

2005 Subaru STI

Stage 1 - No modifications are necessary to run this 16psi peak map. 91+ octane. Raises idle to 900 for easier starts. Free download!

Stage 2 - This map runs a peak of 17.5psi. Requires only an aftermarket downpipe. Aftermarket catback and snorkus removal are recommended but not necessary. Eliminates CEL for rear O2 sensor (when using a catless exhaust.)

Stage 2.5 - With just the addition of a high flow fuel pump (Walbro255 tested) to your Stage 2 setup, you can run this 19psi peak map. 12.XXs in the 1/4 mile are attainable with this map.
