In this video, I show you how to set up a real anti-lag system on a Subaru and possibly other cars. This can be done for cheap, all you need is a switch, or button, and a relay. You also need some way to modify ECU tables like ecuflash, romraider, or cobb.
Here is the link to the forum post where I got the idea:
