Sorry for the hijack but my car uses the same Amal set up (lectron valve) and I'm having boost issues. My Amal was bust so I've unplugged and bunged the hose going from compressor/wastegate to it (was hooked into Amal output :s)
But now I'm having overboost symptoms. Would replacing the Amal solve this? Or if it is a stuck actuator will wd40 and carb cleaner sprayed on it's joins and moving parts and some wiggling unstick it?
