impressive so far - even if fuel limited at 5800rpm.

Where is the 40degC IAT measured?

So good :good:
Interested to see the outcome re hardwiring the pump.
Lmk if you need diagrams.

Is the standard jetpump a consideration?
It can cause a restriction on the return, potentially stalling the pump.

Radium make an upgrade kit with different orifice jets.
Is your system returnless at the rails end?

The fuel rails have been modified so the fuel now enters in the middle and the return is on the end of each rail. The company doing the mapping have carried out the mod so will have to wait and see what happens. The prop is off the car and being sent out to get the middle bearing replaced.
Apparently at 5800rpm all the numbers are increasingly rapidly so who knows where it will end up but i don't think it will get close to 500bhp probably still around 450bhp but with a greater torque spread, just want the car back asap as I haven't driven her since February.
