Hello fellow 08 owners. I've got a catless DP with 3" piping throughout with single muffler on my sedan. Just a little FYI and a DIY for y'all. There is a hose that tees after the wastegate, about 1/4" OD. I took the "t" assembly of hoses off. Notice that the two hoses that follow in-line have hard bumps in them. These are restrictor pills. Yes, two pills, unlike the years before, this model has two. Remove the brass pill from one side and drill to .047". Place the pill back in the hose you removed it from and re-connect to the car. Make sure the side you drilled out is on your right side when standing in front of the car looking at the hood. By opening this hole, the turbo will reach a lower, safer boost level. After I did this I hooked my AP up to it and set it to "live data" to get an accurate boost reading. I did a few hard pulls through to 4th gear and reached my target boost level. I have had no problems.
