Well I've done it I got almost 1100 miles on my DGM 2013 4dr. All I can say is wow. This car feels 100% refined. No jerking on low rpm shifts. Everything feels silky smooth. I have not checked the max boost yet just been in town driving. I'm going to check to make sure I'm in the target boost. Then I'll give it a tank of gas and datalog it to make sure I'm safe. The loping idle is gone just feels like a different car. Other than a K&N drop in filter and Nameless muffler delete exhaust I'm stock.
