Well there is a very easy way to tell if it was a full power or 33bhp ECU, when you rev the throttle and it gets above 6,000 rpm it increases in revs at a slightly slower rate than it did getting to 6,000 revs. The full ECU increases at the same fast rate throughout.

Admittedly I don't have a Sv now, but I remember this clearly when mine was restricted. at 6,000 revs it felt like it lost a tiny bit of power.
