Hello, I'm tuning my Peugeot 406 2.0 HDi 110 RHZ with downpipe 2.5".
I have set 84mm3 and 1.35b with 1450 bar, but I'm not able to reach more than 1350 bar, I have already tried to adjust pump duty cycle but It doesn't get better.
In logs pump duty cycle goes to 97% although I ask for 56,61 max, I imagine PID tries to make more pressure but unfortunately with no result...
Could I have any mechanical fault? Car is fast and only smokes a little but I'm concerned because pump pressure is as stock.
I have attached ori, mappack and mod files.

I have not looked at the file - but you have probably not changed all the SVRL's. :)

You may not have injectors.
Try measuring the injector return line. if the return flow is more than 40 mg per minute at idle, then repair the injectors!
