Static or rising rate fpr
'96 wrx - going for esl live, using walbro 190lph high pressure pump.
Does level of tune/boost effect the type of fpr? Assuming max 6700rpm shift points and hydraulic heads.
When the mapper lifts the bonnet, what fpr will he/she want to see?
Probably not an FSE boost valve?! (max 5bar) - which is rising rate.
The oem fpr - old, non-adjustable, do I just change for new oem (max ?bar) - also rising rate.
If I go mafless, is a rising rate fpr still an issue.
Fse do 1:1 race? adjustable fpr AIR007 (max 6bar)
If I go sard, aeromotive, fuel lab, sx are these 1:1 or rising rate?
If I go for an aftermarket 1:1 fpr, can I run it, without issue, 'til I get a remap?
I can normally read these threads and work it out; but this one's beyond me.
Any thoughts/help gratefully received.

or your better option is to not bother with a fpr, (assuming your car is reasonably standard) and fit a set of 440cc injectors instead which would probably be considerably cheaper !

Oh! 1:1 AND rising rate! Spent 5 hours reading, and still didn't get it. - thought they were mutually exclusive 
Thanks, both, for the speedy replies.
P1, I've got some s/h lateral performance 440cc flow matched/modified injectors (currently, 380's) , ready for the map: haven't chosen who yet. Does that effect the fpr I should be looking at?
