So, is there a popular/ recommended EGT guage and probe/ sensor.? Or do I just go with anything first? Thermoguard??

I don't have an egt. I've been tweaking with excellent results. My only test at present is a handheld u.v temp pistol. After a 3 km sustained 3500rpm 4 gear full boost pull. I jump out, lift the bonnet and take readings, 25 secs later. I know it's funny, but that's my temporary method. I haven't measured more than 480 deg c on the maniflold turbo region. Normal highway drive 280deg C. My question is how much hotter would the gas measure at a sensor probe ? ...compared to the thermally conducted reading I'm measuring.? I'm preparing this tough old disco 1 for a 1500km motorway xmas trip to leave at a beach property as a street legal hack about. I am very cautious now. Having cooked a tdi 300 on another disco 1 in 42deg( when I turned it off at a roadhouse without cooling for a while !)...and subsequent summer trips. Damaged 2 p38 v8s.!! Same conditions. Despite preparation and care.!! **** sometimes happens. I don't want problems this time. Can someone recommend an egt guage and probe that will install simply. All year I'm in alpine cool temps. But that one xmas trip often experiences days of 37-42. I don't want to hurt another engine. Or be roadside awaiting a tilt tray in 42deg with grumpy family again. I'm happy to drive 20kph slower. But I want to know if I need to.
