I tried with the dealer but I literally dropped it off 1 hour before your advice of disconnecting the CANbus wires. I go in for service on the 18th and will re dyno the same week

Have you dyno'd yet?

yeah thats no good... but you gotta let us know all the conditions though. It looks like your on an AWD dyno so i gotta ask if you have xdrive? There are just procedures that Shiv talked about to make sure you dyno your xdrive correctly or it'll go into limp mode for sure.

Other factors are what the temp was outside?... Did you let the car auto-tune before you went on the dyno? What was your auto-tuned boost at the point of dyno-ing? Updating to the new firmware / beta maps would help if you haven't done so already? What other mods do you have?
