To start, I owned it for two weeks before tuning it.
Before the out of box tune from RaceME, the truck ran smooth, and there wasn't anything noticeable going on
I tuned the tuck and took a week or so to find out the truck would shake pretty well when started and have the EB on.
After about 5 minutes of driving or letting it idle for 10 minutes, it won't shake when the EB is on and getting up to temp
I have also noticed sometimes, when starting the truck and the EB is off, the truck will have a hard time constantly idle until I rev it up, hold it for a few seconds, and then release
I live at 5,000 ft; I have noticed it will act like this 98% of the time in winter. (no block heating) Also, when I travel to higher elevations, it's a cold start, regardless of the time of year.
