hi all problem is that my cossie will only boost to 15 psi

car spec
greens,3 bar,-31,chip stage 3 , scorpion,4x4 intercooler,bleed valve ,

i changed the amel valve cus it would only boost to 10 psi now the bad boy only hits 15 psi standered turbo its 2wd

1 acurater i have hits about 19 psi and drops to 15 psi the other hits 15 and stays there car still pulls well

any ideas would be top

velocity

does the new amal valve have standard restrictors in it.there should be 2 plastic inserts in two of the 3 pipes on the valve,but if you have that level of mods you may need to modify the jet size,check the old valve and see if there missing or oversized, and if different from the new valve simply pull them out and swap them over and have the new valve the same as the old.

could it be that 1 of the acurators will only hit 15 psi and the other has a weak spring as the 1 that hits 15 and holds is not that old and i might have bin sold the rong 1
