Krypton tuning - still done?

[Barreti]

Chatting to a mate who is as old as the hills, he asked me if I'd ever had the Griff Krypton tuned because he used to get his old cars done every year.

I know what this is because I'm no spring chicken myself, but I've never heard of anyone on here getting their car Krypton'd
Is it necessary? Is it worth doing? Just what does it do exactly?

Until a couple of years ago I lived next door to a guy who had a Crypton machine in his 'underhouse workshop' (retired Ford main dealership owner).

He knew how to use it, and was able to quickly sort out some timing and ignition issues on one of my cars...for the price of a pint.
