I've had issues... Long Cranks, 6-8 seconds start-ups with codes showing up with the BT tool: : which is, drum roll; a shadow code for "fuel high pressure on enabling of injection: pressure too low"

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.
