The Hiboost tune it comes with is real close to perfect. i just installed mine yesterday and it runs as smooth as stock. It includes everything you need to install. Just be sure to solder the connections so there arent any wire tap problems in the future.
curious on the MPG after the Hiboost... can you track it and get back to me?
can you adjust for boost....low vs High...etc... econ and perf settings? It would be kool to adjust on the fly...to get the best of both worlds... My buddy only gets 4.5 mpg with his stock STI on the trac... hell of a price to pay for 300 hp
