Slant 6 Turbo 68Dart Project

I want to. I need to find a mount that will hang off a suction cup on the back quarter to see the exhaust. I saw it during the night when I punched it on the freeway, hit 6psi and the mbc limit hit, and I adjusted it more since then, but anyway - the 6psi opened the wastegate, and it "held" 6psi, but you could see a plume of some kind of smoke once I punched the gas. It may just be that the jets are too big, and dumping too much unburnt fuel. I may experiment with a BRPV and drop the jet size soon.
