Just a word of warning - the Morgan Motor Company had a dispensation on some of their models for the lambda reading. I remember my 4.6 Plus 8 would not meet the 1.03 and after querying it with Malvern I was told that it was allowed to go up to 1.08. The MOT testers have a little book with all the settings in, but rarely refer to it because the majority of cars are from 0.9 - 1.03. Just might be worth checking out.
