Update, I finally installed the DME stage 2 tune a week ago. I have not installed the cat-less down pipes yet. The car is faster (seat of the pants) but I am sure installing the down pipes will make a bigger difference per DME. There is no difference in gas mileage with the DME stage 2 tune from stock, at least with normal driving. I am still getting 21.7 MPG around town. I am also going to replace the original Bosch plugs with one heat range colder plugs. Hope to get this done in the next couple of weeks.
