It may need to be updated maybe.
The car runs perfect, no waste gate rattle or any rattle anywhere. It was on map 0 so they turned it off. I got it from the auction with my brother and it came from a pretty big GM dealer. Paid $11,700 for it has 79500~ miles. Just to be sure i got the 12 month unlimited mileage platinum coverage at dealer cost so hopefully that will help me cover if things go wrong. Pretty happy
I plan on running map 5 and 20% e85 mix on occasions - 93 or higher overall.
