Hi there, your english is not that bad, there are british people on here that do not have as good a grasp of the englsh language as you do :)
Running on stock engine internals, i would recommend 7 PSI or 0.5 bar maximum, if you lower the compression you can use more boost.
hope this helps

That is wrong, excess fuel wont matter, its has to be fuelled correctly.
yes 0.5 bar is the most you should run on a standard engine, if you use a thicker copper gasket form http://www.ferriday.co.uk you could run more boost, probably close to 1 bar :)
