There is no need for them usually but this is a special situation.

Its not actually for a car. Its for the bike shown at the bottom of the page in the thread below.

The injectors will be too small and all i have to change the fuelling is a Powercomander 3 which gives basic control of an aplpha-n map and not alot more.

I can't replace the injectors for bigger or turn the fuel pressure up as it will bugger up alot of other parimiters like warm up and accel enrich that i cannot re map.

So the plan is to use the best comprimise which is a rising rate FPR that will only increase the flow of the injectors up top when on boost and therefore shouldn't effect the other parimeters so much.

All a bit bodgy and not the way i would do it, but my mate only has a small budget and therefore i have to find the solution to fit the cost!
