Thanks Madhouse, good to know. It sounds like it will be money well spent. Not really planning any mods on my 05 gt manual for a while yet, but being able to default TC off , improve the drive by wire throttle response plus a little more power will be worth it.
TC can't default to off. If the tuner turns it off, it's off - - no turning it back on with the switch. It can be re-activated in the tune obviously, but it essentially disables the switch when turned off.
