What's normal EGT?

An EGT gauge was installed using the hose-clamp method by drilling a hole into the exhaust about 4" from the turbo. Now I'd like to know whether or how much difference the temps are between that location and coming off the header location.
The X runs almost exactly 400 during around-town driving at 70 degrees. Accellerate hard from a light up to 70mph and the temp gets up to 700.

No chip involved. Are these temps about what's expected from a standard setup?

Pre Turbo: My EGT 500-600 at 40-60MPH, standing on it for a few seconds from a roll reaches around 800. This is 30-50 degrees outside.

My pyro is in the driver's side header. I range from 550-750 depending on the amount of right foot during acceleration. If I role smoke (aka hammer down) It keeps climbing 1000, 1100, 1200...

Would it be a decent assumption that installing the probe into the header might add 150-300 degrees to the pyro readings compared to adding it up near the turbo? I can't get the pyro over 800 so far.

Yes your probably right, the key is to provent you turbo from burning up. Most manufacturers tell you to drill and tap it into the elbow of the manifold. I guess if you run it too high there maybe the theory is you still have some room before you burn the turbo up.

Give yourself more room than that. The post turbo reading can vary as much as more than 500 degrees! At normal crusing, they're pretty close on my gauges. I have pre and post. But at full on balls to the wall, I (used to) get over 1400 while the post gauge still had yet to get over 1000.
