Ajustable fuel regulator

Hi,How much would a Ajustable fuel regulator cost and where would I get one from,thanks Ken.

£98.00 dead easy to fit worth every penny, put one my 350i
Not to be confused with the std. adjustable one as fitted on larger Wedges.
Do a search for power boost valve or FSE.....heres one....www.proven-products.co.uk/products/fse_power_boost_valves.htm

Funny thing though, 2 years ago they were only £60.00

Just been having an internet rummage, and it appears that the price hike applies if you buy the kit with fuel rail adapters etc.
If you buy just the reg. it's still £69, but then I guess you need bits of garden hose, tie wraps to stop the fuel leaking, chewing gum to hold the valve to the hottest part of the engine etc etc.
I'd be interested to hear the opinions of the real experts regarding the 390SE's FPR: it is adjustable and has the vacuum tap for the plenum; is the FSE unit still a worthwhile upgrade (ie is the rising-rate delivery curve still worth having or did the adjustable Rover unit do that anyway)?

The rising rate regulator is a bodge, albeit a bodge which will mostly work and the engine will likely be overfuelled. Far better off raising the pressure to a reasonable level in the first place and mapping the thing properly

All very well if your ECU is mappable

When I had my 350 tuned back in November, they took the rising rate regulator off and put a standard one back on. The car was then tuned with 97 ron fuel in it, timing, new plugs etc and it felt a little faster and more responsive
I havent ruled out trying the adjustable one back on at some time.
