My RV12iS is ready for the very first flight. I have concerns about the following fact:

Before engine start, fuel pressure with one elec pump 3 bar, with two elec pumps 3.1 bar. After engine start: fuel pressure with two pumps 2.8 bar, with one pump 2.7 bar and the „low fuel pressure“ warning comes on.
Engine running smooth.
Then, when increasing rpm above about 3000rpm, fuel pressure comes back to normal, 3 bar.
Whats wrong here? If i reduce the rpm again to 2200, pressure with 2 pumps again 2.8 bar.

Any idea, is this a problem or not?

Is this an issue to install the fuel pressure damper?
