Okay Icontrol 260 guys with tunes, here's a fuel pressure question for you........
How many of you actually checked it and what readings did you get? How did you correct it?
Mine is low at about 52 psi. How would adding a FPR help if the factory is already a returnless style system. If you make it a return style with a regulator, how is the pump going to make more pressure than it is now? For example my pump is pushing as hard as it can against the fuel rail and making 52 psi.
I was told more voltage to the pump would increase the pressure and that makes sense, they do it on boosted cars.
Any suggestions? I guess I can tune my ski around my individual pressure no? It does hold steady, just doesn't peak at the factory 58 psi.

this is a very common problem with the newer skis. Fuel pressure is terrible inconsistent. The aftermarket tunes are based off of 60 psi static fuel pressure.
What you do is install the Riva RRFPR and set it at 60 psi static fuel pressure
Lots of good information can be found in this thread

Is there a non rising rate regulator available? Can the Riva unit do this? I don't need a RRFPR on a basically stock ski do I?

The Riva can be set up as static or rising rate
You will want to set it up as static if you plan to tune the ski with V-Tech or other aftermarket ECU as all of the tunes are written based on 60 psi base pressure.
If you plan to leave the ski stock then you don't need to worry with it.
