PainfulTeg

I know, I know it's a mitsubishi turbo, it's actually my uncle's 90 laser rs. I was attempting to evaluate what is wrong with his turbo. It ran 7 psi stock, but it's got a lot of miles (158K) and for a few weeks, the boost was creeping to 9 psi. Does anyone think it's the wastegate vacuum that is failing? As of now boost does not reach higher than 0....haha, so she's a dog.....if anyone can comment I'd really appreciate it....Thanks
