Does anybody know what the fuel pressure supposed to be at WOT for the 2006 through 2009 jaguar 4.2 supercharged cars with a single pump?

For completeness, PTEC is what the early S-Types use. Newer ones have Denso.

Ignoring diesel.

I was just curious, imma assume 43psi is the correct amount but if anyone pillows for sure or has a different reading, please chime in.

At Wide Open Throttle, the fuel pressure for the SC engine should be around 500 kPa as shown above in the chart.
