750C is the limit for turbo inlet, put your own safety factor on that. More boost (and better intercooling) lowers EGT's, more fuel raises EGT's.
Unfortunately your probe in the exhaust down-pipe isn't much use, the temperature across the turbo continually changes, rough rules of thumb (100C drop, 200C drop etc) either drop performance un-necessarily or endanger your engine. If you really need to know, you need the probe in the manifold.
Make sure the probe is long enough to reach the centre of the gas stream.
