The best i come up with is 3.8 to 4.1 Bar, there are special adaptors and testing equipment to do this, i suggest that it is done at a dealer as you can damage fuel line connections if not done correctly.

Have you check mechanical timing? Are the crankcase breather hoses cracked? have you tested the MAF?
