ok, now it's more clear (sorry for my poor english)
i know that this is an insane idea, and so first of all i asked if it is possible or if the transmission will explode ^^
a more reasonable idea is a "soft tuning", but i'm not sure about some modifications: for example, a bigger airbox with a bmc/k&n filter, the throttle body from a ga15 engine, removal of first cat and a fuel pressure regulator can give some improvement, especially at low rpm range? you can do these modification without touching the ECU?
