You know, I've gotta stand up here and support Flecha's comments. When the whole DMD thing started getting talked about I too got caught up in all the talk and bought one and got it installed at Ford. I took the ASP UDP off and put this on. As soon as I drove off it honestly felt like I was carrying a carload full of people. It's like he said, the revs don't rise as quickly and there's not the 'snap' throttle response when you tip into the throttle ... needless to say at the first opportunity I too put the UDP back on and sold my DMD. The change in smoothness was also minor as mentioned. Obviously others have had different results, but mine were not of the positive kind ... and ya I know about the crank whip thing ... that's my opinion.
