Well, that's your first mistake, IMO.  For racing, I would definitely
replace that thing with a 270 sweep mechanical unit.

If this is the stock TR6 gauge, I would suspect the voltage stabilizer;
which is a little metal can on the back of the speedo (I think).  The gauge
is voltage dependant and expects a 10 volt (average) supply.  The VS chops
up the voltage from the battery, to create a long-term 10 volt average to
the gauge.
