Macjohnw,
Chipping an engine has and will be a very cotentious subject. The only way of getting more power out of an engine is to improve the flow of air through the engine or increasing the thermodymamics of the engine. Increasing the flow can be done by bigger valves, higher lift camshafts, bigger ports and bigger/faster outflow of gas and a higher compression. All of these require / demand a higher fuel flow. Chipping is fine tuning the timing - making it earkier and nearer to detonation and adding more fuel. The dyna-tune people has more tricks up their sleeve(s) than a lorry load of car hijackers. The only place where a truly reliable dyno reading can be taken is in a laboratory under stringent control of temp, pressure, humidity, etc.
I do not know how old you are but if you are one of the less young persons like me, you will remember the times of the hi-lifting door handles, the high compression hubcaps, the orange on the aerial, the exhaust pipe with nothing in it, etc. Some drivers swore by it that removing the silencers and making more noise, made their cars faster AND lighter on fuel!!
I would like to suggest that you and all the potential "chipping" people contact Jakes Venter. He is the technical edditor of CAR magazine. He also writes for other magazines and is very, VERY knowledgeabe, has an engineering degree to give some status to his opinion and in fact has always been more than willing to discuss how to truly increase the output of engines and at what cost. Maybe Simon should contact him on behalve of the Pajero club and ask Jake to write an article or articles on chipping, dyna tuning, etc.
How about it Simon?? Regars, Cloyd
