Does any one know what the maximum (safest) boost you can run on a standard EVO VI with standard pistons Etc.

Thanks in Advance

On a IV I would say 1.7bar peak in the mid range. For longer life, keep to 1.55bar

well, we had some cases in sweden of bended con rods and melted pistons in cars running standard internals and more then 1.4 bar boost. i would say - do not exceed 1.3 if you want to stay within safety limits. you can run more, but for short periods of time, otherwise the heat and steresses that develop will risk the engine.
