I have the dptuner in my sig and 140 extreme does smoke quite, not sure about the aggressive. I would give Jody a call and ask him. He will be more than happy to help you. I called before I ordered mine.
I have no idea what kind of gauge that is but it doesn't matter because it does not come with any kind of gauges. They are just showing you the mount for the rectangular style switch. Thats the style switch I got but I fabbed my own stainless steel mount.
140 aggressive is the illustrious "smoke" tune. It has a whole lot of tip in on the throttle. The tip in spools the turbo on the bottom end real nice but it will smoke like a freight train until the turbo lights.
