Garage List
423 awhp / 478 awtq on AWD Dynojet

-Dinan Stage 1
-Dinan Cold Air Intake
-260GT 100 Octane
-DSC & DST Off (this was the only way the engine wouldn't downshift, but it would only work in Comfort mode). Holding down the DSC button for 5 seconds would always flip it back to Comfort mode. Spent about 20 minutes fooling around with the settings with the technician and Comfort mode was the only option. I'm sure others have had this issue...dyno noob here.

Not that impressed with the numbers compared to what others have posted here with BM3. Would Sport + really have made a difference if I was somehow able to make it work? Maybe I need to reassess Dinan...That said the technician said the power gains were smooth as hell.

Technician commented that his AWD dynojet typically results in a 22% HP loss when measuring atw, so he thought ~516hp was the number.

Wanted to share a video because the sound was intoxicating in person. Funny how we never get to truly hear our own cars!
