MDS Off - Love the truck again!
Hey guys - first post. 
I was a 5.9L Dodge Cummins 4x4 owner and got rid of it after I sold the Mastercraft for a new F150 4x4 and the forum guys told me I'd be back. I blew them off, but they were right. When I got rid of the F150 and switched to a 2010 GT500 (620 hp / 620 tq) and eventually needed to go back to a truck I didn't even look at the Ford, Chevy, Nissan or Toyota, especially with the local dealer having it marked 10 grand off sticker. So now I'm in a 2010 Ram Lone Star 4x2, 3.55 gears, and Cool Vanilla and LOVE IT...but the love was fading until yesterday.
Shortly after buying it I installed the K&N cold air intake and the Superchips 93 octane tune. This made the truck come alive and placed the shift points in an optimum range. Just changing the shift patterns alone was worth the cost of the Superchips. However, once I installed the Superchips and went on a road trip I quickly noticed what I thought was the torque converter locking and unlocking way too often when on cruise around 60-70 mph. I played with all the shift schedule combinations that didn't require an extra $ download, but to no avail. Finally I decided to turn the MDS off (although the ECO light continues to work) and now the truck performs flawlessly and I no longer dread driving it at low highway speeds on cruise. And as far as the gas mileage, I haven't been able to tell any difference. Maybe it's my imagination, but now it feels like I have significantly more engine braking on decel.
Now that I have MDS off I can add the Flowmaster 50 SUV muffler that I liked so much on my Cummins. Then it will be time for a leveling kit and a set of 4.10 OEM gears (expensive but best guarantee to avoid the whine). The truck already feels as quick as my Cummins with the Edge Juice, and I'm sure the gear change will be a night and day difference, just as it was when I did it on the Shelby.

And yes the F150 feels like a slug, but it felt that way from the day I bought it. Sadly though, now everything feels like a slug after getting out of the Shelby. My 9 yr old son accused me of suffocating him because it accelerated so hard it pushed him back in the seat and he said he couldn't breath. LOL
