Default What temps should I be running at roughly?

I just got around to hooking up my pyro gauge and was wondering what kind of temperature range do some of you run around cruzing at roughly the 65-75mph range. Mine is running at roughly 500-600 area which seems low maybe not though. Only got a 90hp tune to it with some mods seen in my signature. Just wondering. Runs 7-8 when get into it. From what I read the 1200-1600 is the danger zone. Just wondering if that like I said seems low like maybe I didn't stick the probe in far enough or if that's seems normalrange I should be in.

What kind of mods do you got? With my setup and a ported turbo horn "which didnt do much for egts really" I am running about the same thing. Some may be able to correct me on this but 1100-1200 is about the final degree of safety when towing or working it hard. You can even take it up to the 1600ish range if your passing or something but dont sustain it there for extended periods of time.

X2... If you hit 1500-1600 for a few seconds its not a big deal Just dont hold it there for a long time.... Thats when melting/cracking/breaking happens

my lbz runs around 500-900 just depends on the terrain, i hit 1000 going up a long hill with no load but on a flat straight piece of road it runs 600-700 at 65-70mph usually
