when you say about pre-detonation may it have something to do with the way your engine is setup ? timing(to advanced/to retarded)? boost? fuel delivery? place where the gas was released into the system? regulation of the amount of gas required? etc etc causing this problem???

i cant see how this (registered)product can be allowed to be sold if it may cause engine problems

Isuzu make a B series marine engine (the 4BG1T) which runs more than 20psi boost. Marine engines are a market where reliability is rather important. Every marine engine brand has high boost, high performance diesels, it's been well proven.
On road cars BMW run more than 42psi boost in their highest tune 3 litre diesels (200kw, 600Nm). Their competitors aren't far behind.

Where I'm going with this is the risks and rewards of high boost are very well understood, you can buy engines which run very high boost and they come with the standard warranties.

The risks of lpg fumigation aren't well understood and it isn't well researched. Engines have been damaged, but also people run it without apparent problems. There isn't enough understanding to say this amount is safe and this amount isn't. But all the engine manufacturers stay well clear. Not one manufacturer has produced or advocated such a system.
