Default Decreased Compression Ratio vs Boost/Timing on pump gas - 09-19-2020, 03:06 AM

What is the maximum boost one should be running on regular pump gas (95 RON / 90 RM2) + WMI before there isn't any further benefit?

At what boost would it be worth considering a slightly thicker head gasket (0.052") to slightly lower the compression ratio, and thus allow improved timing?

Note I don't have access to cheap E85.
