OBD2 VR6 fpr

[fla 9]

Ive converted my car to obd2. I think the original fpr was 4bar but the obd2 was 3cbar or 3.5bar, although this was for a 2.8 engine. If i replace my fpr what pressure should be used? 4 bar?

Thanks

The ecu can cope with 3 or 4 bar, but 3 bar seems smoother probably from longer injector timings.
