arvail boost valve

[Jazmac]

has any body got one of these arvail valves fitted?? i have one and since i had it on my car stutters at top pressure well its set at 0.9bar so not off the scale, it drives lovely untill it hits the top of the gauge. i cant revert back as the small pipe with the restrictor was shot all perished so took the restrictor out and bin'd the hose, i have fitted brand new plugs set to 0.7mm i dont think its a spark or ht lead fault as the car would run bad all the time, i also have a uprated walbro fuel pump so its not a fuel pressure cut off fault, im thinking of getting a dawes

I could be going up the wrong lane here but i have an "armval" manual boost controller and it feeds out a very very consistent 14.7 psi at full boost with no drop off whatsoever. No running or idling problems at all. Amazingly i set it at its minimum and then got going. Reached 14 psi so did one more 1/4 tunr and got where I am so it must be capable of holding much more.

Got it off ebay for just 24 notes. For sale in feb though as getting tek3 with 3 port boost solenoid. Not bothered if I manage to sell it or not though

This is it below
