So, recently installed a screamer pipe from external wastegate on my D16 civic, but having a few problems... When the wastegate is not connected, my boost gauge shows about 13psi on peak boost. When the wastegate is connected, I don't think I've ever seen over 7psi all the way through. When it's connected, at around 5k (when I should be hitting peak boost) - theres a strange noise coming from the wastegate (sounds a bit like a frog). Any ideas on what this might be? The set up is; vac pipe out of a nipple on the side of the turbo, which is connected to a copper pipe, which leads to the side of the wastegate. There is a nipple on the top of the wastegate with nothing connected (also tried a bolt here as well which didn't change anything). Cheers
