just wondering if MDS and the converter lockup are related in any way? the reason i ask is a good friend of mine uses his 04 Cummins for sled pulling and he can electronically lock his converter. this seems simple enough to do so i was wondering if i manually lock my converter will it help keep the MDS on through hills and head winds?

Ya I was reading an article about MDS and when it goes on and off the converter slips so that you dont feel it as much between the change. I think thats why you can feel it jerk sometimes when you have the Superchips tune because it keeps the converter locked up.
