DSS Ultimate II

I need some more information on what pressure to set them?

Hello! I pop tested mi afn injectors with dss´s at 270bar first stage, a bit noisy injection. But works well.

is there any data/dyno about dss uII vs. R520? You can see mods below. Head is going to porting and maybe slightly bigger valves and 12mm head is ordered already. Was thinking about selling races and changing to dss.

I think you should call Findiesel about that IIRC its around 10% gain over R520 but it might be higher.

heard rumours about pretty impressive gains when changing just nozzles. Same program and no increases on emp and 15-25hp gains. I think ill be trading races to dss u2
