The shifting is going to be rough, but will smooth out. Most people try to do a re-learn process which involves a few wide open runs and a few half throttle runs both 0-60 or so. If not, it'll take about 2 weeks(in my experience) to get it smoothed out.
As far as MPG goes, 320 miles is not a full tank for me so I'm assuming you're going off of the dash. If you're going off the dash hold down the toggle button to reset the AVG MPG number and you'll probably make yourself happy till you can see what it does over a full tank hand calculated.
As far as the weird tranny thing, it's happened to me a LOT. With the Innovative tune I have, it does not happen, but something with the canned SCT stuff it does happen to me in one turn if I'm coasting and slowly accelerate around 20mph or so. Not sure what to tell you there other than carry more speed around the corner or less speed.
