Okay. So i have a stock 87 turbo. I was looking to get a new exhaust and a wideband air fuel gauge. What do you guys recommend? I remember reading somewhere that the wideband should be mounted 3' from the turbo is that true? Or can i just get the turbo elbow with the bung opening for it? I want to turn up the boost a little more than stock. Maybe 9-10 psi but i want to keep and eye on my running conditions. Any help would be appreciated. Thanks
