Also a SK guy here. I drove a guy's truck that was done at the diesel performance shop in Regina. They use a tune from out in Quebec. I don't think they gut the DPF either just drill holes in it and they put a little U shaped piece in the turbo actuator to lock it in place and claim similar effects to a pukedits nozzle ring turbo. At the time and not having any knowledge it seemed like a good idea but now knowing what I do thanks to this forum I wouldn't take my truck there if they paid me.

As others in this forum have suggested, Contact Unilevers. He's a busy man but he WILL sort you out.
