:runaround: What have I done? I did not do my homework I guess before I purchased this new rig, This multidisplacement engine is really "so far" nothin I would write home about. I can't figure the damb thing out. 2000 miles at this point and the only alter was a muffler and twin tail pipes at the right rear. Just for some sound! That is when It all started, I think,ERRRGH! Between the autotrans, and the running on 4 cylinders at any given time it seems, and having to turn off o/d & or tow/haul just to drive it in town, is a pain in the ass. And with the new exhust, it sounds like I got a loaf of bread stuffed up my pipes {durring MDS}4. Any Ideas, thoughts, or solutions, send em this way. Thanks!

I have the same issues but so far no answers. I am looking for some way to turn off the MDS completely and I hear it can be done with some aftermarker products but so far, I haven't found anything like that.

multidisplacement engineS SUCKED WHEN CHEVY HAD THEM WHY WOULD ANYONE THINK IT WOULD BE BETTER...


NOTHING LIKE AN INGINE RUNNING JUST TO MAKE PISTONS MOVE FOR NOTHING DRAGING DOWN THE REST.........IT'S A LOSE LOSE:banghead:

I am sick of the MDS already and only have 2100 miles on it, dealer says it's still learning and nothing he can do, this is normal. I hate it, I wish I had known before I purchased it, if you or anyone else has found a way to turn it off or adjust it to freeway speed only please let me know.
This thing starts up and idles on 4 cyl, I can drive it all day and it not change out if I am easy on it, here's the scary part, MPG is the same for me, it sucks.
HELP!
