The easiest way is to install an OBD gauge like P3 (what I have). This monitors boost, air-fuel, ignition, etc.

Both options will give you a window into your fueling - air/fuel ratio will answer some of your questions.
Thank you for the information.

What are the chances of the S65's Fuel Pump going bad in the first place anyway.

The reason I didnt get it changed out in the first place was because reading through years of feedback , and there was never much complaint about the fuel pump going bad, unlike the HPFP issues on the 335's
