Had a couple of boost gauges on my car to check her over and found that she was boosting up to 4 PSI and that was it. Any way checked for leaks - none found! Any way if you rev my car really quick up to say 2500 RPM and let off the dump valve gives up a big chirp. Never seen this when car not underload. Any way checked over the engine I have got in my car has had the Amnal valve chopped so I just have a tube from the Charger to the Actuater. So I carefully adjusted it turn by turn. Any way I got it now so if you rev it and let go there is no dump valve noise but there is a wicked chatter from the waste gate. Boost sseems about 8 psi so happy with that. But why is the dump valve not dumping now??

Cheers as always viewers
