Wrong software version was downloaded at initial install causing drivability issues and deactivation of the brake vacuum pump. Issue was completely resolved on the first return visit and performance has been flawless the past 2k miles.

I had some issues but they were only brought out because of the stage kit.
The higher boost broke then intake tube at the map sensor [bad electric weld]. The map sensor hit the ac compressor after the tube was replace and they had to shim the IC out to give it clearance.
Both issues were due to then the intercooler and tube were replaced after an accident. If I had not been run off the road neither issue may have appeared at all.
