Update: spent some time on the phone with Andrew from Tune My Euro and when I did the DPF delete I didn't delete the EGR cooler. The shop instead put a block off plate on the tail end of the cooler where it attached to the DPF. That whole thing needs to come out and the cooler has to be blocked off with a plate where it attaches to the turbo manifold. ALso need to delete the vac switch on that cooler and plug that vac line. We're thinking that is what is causing the issues as I'm losing boost/vac through that cooler. Pro tip: don't buy an incomplete DPF delete kit. Get the good one from Andrew!
