I need to go back to VinnyTen to dyno. My car originally dyno'ed low because I was running on snow tires and a restrictive 535 exhaust. I dunno about your results though...No change in your tune and somehow you gained another 40whp and wtq on top of your original gains seems strange. I am skeptical that the JB is good for 80+whp and 100wtq with just fugging with the MAF readings...
Please post up a pic of your dealer invoice of the work done. Brand new 2014 550 with massive boost leaks is insane. Curious to know what they fixed/touched. I've scanned my car with the BT tool several times before and it never showed any codes indicating anything is wrong.
