The addition of rs4 valve is optional when running a map that requests 130 bar and you should already have an uprated hpfp to provide the requested 130 bar.

Spot on
Some standard valves crack open too soon ie at 120-125 bar when the standard valve should be good to 130 bar. Therefore your map could be requesting 129.9 bar and your standard valve crack open too early and not make the requested fuel rail pressure required/requested by your map. Consequence of this happening? Probably pulling timing/boost and reducing power.
The RS4 valve will crack open at 136 bar, so making your 129.9 bar requested fuel pressure possible.

+1 It allowed me to run higher rail pressure map upto 135bar 4000rpm onward, which gave me a better combustion and allowed a small window for more timing advance at the top end.
ROH ECHT:
Thank you all, ordering the rs4 valve now ;] Can't wait!
