hi stu thanks for your reply. i started off with the amal valve connected and tried two ecus one superchip and one standard ran down the road and a massive over boost of 1.5 bar with no ecu boost cut limit on either ecu, so went to plan b tested amal valve and it all seems to be working correcty. thinking that the amal valve was faulty my only route of action was to fit a bleed valve now this time no intervention on boost cut on either ecu and wil not boost under 14psi ? so must be amal vavle i thought. so fitted standart actuator wich is soggy as S**T tried both ecus, WITH amal valve STILL 1.5 bar WTF ?? so checked every thing twice connections wires ect..stil no luck so plan c fit bleed valve and uprated actuator with either ecu and wil not run less than 14psi hmmmm. at this point ive just done a rebuild on the engine and i want to run it it and dont wanna damage the enigne so gone back to standard actuator for the time. wen ran in i intend to purchase a -31 and use the bleed valve as i do not trust the amal set up. i know this is a way round the problem but not the right one, any ideas would be a great help, thanks guys. btw both actuators set up using half hole preload. and tested actuators by connteced to a pressure gauge and compresor to check operation.
