They are saying it's an S480 with the stock unit still in place. Only other items mentioned are H&S Mini Maxx and DPF delete. Oddly they didn't mention EGR delete, even though it looks to be gone from some of the pics they posted on FB.
No gate mentioned either, wonder why? I wonder how much the factory gate can handle. With the tuners I've heard of 30 pounds of boost I think, stacking another big turbo on that and I think the stocker might be maxed out.
Only thing I noticed was what looked to be one of those relief valves, like what they use on the cummins set ups. Maybe someone else has more info.
