Hey just got a set of gauges on my truck yesterday and took it for a drive, I turned the pump up 2 turns on the fuel screw and I have a set of diesel care and performance 40 hp injectors. Same size hole just different spray pattern.
The first test drive I only got into 3 and ran about 900 egts nothing weird there the truck revs to fast to put some fuel to it, but after I got off of work I went on the interstate and opened it up my boost gauge went to 35psi which is not to suprising my dads similiar truck pushed 30 but has an intercooler so mine should be more. The reason im worried is after about 5 seconds and full boost my brand new glow shift guage was showing 1800 degrees thats the most ive seen but even on normal pulls I still see 1200 and I know that these cummins dont like more than 1300 unless for short 30 second pulls so is it possible that my truck could be running that hot has any one else with a 1990 no intercooled truck with same size as stock or stock injectors turned up 2 turns on the fuel screw seen anything that hot. Should I try a different sending unit or is the guage just that inaccurate has anyone heard of glowshift gauges are they quality
