A friend of mine has a cupra IHI with 360hp and 330lbs/ft.
Before the internal mods it had 325hp and 365lbs/ft.
With that amount of torque the 3th and 4th gear was completely ruined so the tuner has limited the torque to around 330lbs/ft.
The gearbox has a Quaife lsd.
So be carefull with that amount of torque
