I've noticed a few things on the Ultra ever since I installed it on my 2014 2500. I have jumped out in traffic a couple of times, hard on the throttle and instantly off to get slowed down and I noticed a weird idle and my rail pressure was staying abnormally high. Also the trans tuning doesn't seem to change much in that department. The top two gears seem to be weirdly soft and kind of like it slips in instead of a firm shift. And the turbo seems like it don't spool smoothly sometimes. Also it doesn't engage the exhaust brake on cold mornings like it did before for quicker warm ups. May need an update but I am having pure hell trying to get the update. Been using Apple computers for too long I guess.
