Gauge/Scanmaster

[foregn2]

If I buy a scanmaster is a knock gauge necessary

No, not unless you want an audible knock gauge.

IMHO an audible knock detecter is almost as important as oil for anyone tinkering with a turbo Buick. Caspers seems to work great.... and you don't have to buy the gauge... just the detector.
