Also thrown CEL's at partial low throttle while going up ramps. "Engine Malfunction, reduce power, blah blah blah" But the X responds normal and doesn't have reduce power at all...

I'll be going to the dealer soon myself... Already took my Stg 1 out, and I still get these problems. And some of these above problems were occurring before i put the tune in, so don't say it's a symptom of the tune.
As I've said in the past, the N55 still has the same issues the N54 has/had.
did you get that code read off of the n55 code list? the n55 and n54 have different codes
