I would contact whoever the tunes came from, express your concerns then inquire about an update. You have to remember all cars are different and react differently especially when talking about a canned tune v. a CDT. My point is it May need a little tweaking to get the car exactly where you want it, but unless your experienced leave the tweaking to the pro's.
