I installed a 1715 Micro Max Superchips tuner in Nov. 07 and for what I spent vs. what I got I've been happy [$209.00]. Lately when the truck is cold and down shifts from 2nd to first it will down shift hard, not every time. Only have 57k on truck and was wondering if anyone has had any of the same problems. Running performance setting with preprogrammed shift points.

 

a hard downshift when the truck is cold is common I think, with any set-up. My truck shifts a little abrupt too when I don’t let it warm up some
