I detailed it earlier, but large amounts of surging and bucking when driving at slow / low throttle situations, like neighborhoods. Enough that keeping consistent throttle application was difficult when it got bad. Anything mid throttle or better was fine. I do most of my driving around town at <30% throttle, so this was super important to me. The tuner basically threw up their hands saying it wasn't the tune and that I had bad parts. Sorry, installation of a blower on a car that was fine before doesn't suddenly make all these other parts go bad.
Also the idle was kept super high around 950-1k, which seemed ridiculous. They said it was required. I've got that tuned lower as well with no issues and can probably still go a bit lower. Interesting to note, if the idle is kept fully stock, engagement of AC will sometimes cause the car to stumble enough to die. Raising it 50 to 100rpm fixes it. That took a while to track down as I thought it might be vct related at first.
