Another update. The 249 RWHP was just one pull with the stock tune. The others have all been 235-237 pretty consistently. So, 249 may have been a fluke.
That said, they figured out how to get around the TPS/Commanded TQ issue and it went up to 275 RWHP!!! They didn't say how much it gained down low. Now on to the VVT tuning. Hopefully there's a bit more they can get from that.
