OK,so I'm going to do a bit of back pedalling here.Having been sceptical about the necessity of a pyro/EGT gauge I'm going to bow to the wisdom and advice of the many members of this forum who have fitted one and fit one to my truck.However there are a few points I am unsure of: 1.Where to fit the sensor...pre or post turbo? 2.If fitting pre turbo (to the manifold) is it necessary to remove manifold and turbo first or has anybody fitted one in-situ? Surely any stray metal shavings being blown through the turbo would be a disaster,right? 3.Any recommendations as to which make of gauge to go for? Due to poor availability and high prices over here I'll probably be ordering one from the US.Seen some 'Prosport' gauges which look pretty good. The truck is a HDJ80 with 1HD-FT by the way. Thanks for any help.
