all i do to turn off MDS is keep it in 5th gear,same milage,up untill 55mph.

 

if i remember stock is 106 mph,5800 rpm redline and 5600 rpm 1-2,2-3 wot shift points

 

Yeah turk1270 is pretty dead on. Reach 110 mph and u feel like someone stepped on your nuts as that other 1/2 ton pulls ahead. Learned that the hard way! Shift points are at 5600 wot 1 through 3 with the limiter bogging and dropping at 5800. My opinion, go to advance tune and max the speed limiter out to 140 then move to shift points. I originally ran with SC recomended 1-2 6200 and 2-3 6100 wot with redline at 6400. In my case the truck would nose dive then surge to second and 2-3 was just plain off. I tried out what someone on here had luck with; 1-2 5950 AND 2-3 5950. World of difference, smooth and crisp power transfer with no lag. Id try a few different combos (am i off topic? i tend to ramble on) but i was about to return it before I downloaded this tune. Just keep the 93, max the limiter, turn off MSD and play with the shift points. Enter tire height just to keep ur speedo in check then just hit OK on everything else and save. So i guess there is a little tweaking to do after all lol. But you'll be happy you did, there is a fine line between awesome and aweful with the SC. Find the sweet spot for your truck and you'll be stoked.
