X5 (F15) 30d xDrive - Gear Downshift and Turbo Lag

Hello everyone,



until now I have done over 5K miles in highway and I'm worried about the performances of the Gear and of the Turbo, when it has to downshift, mainly from 6^-7^ to 5^-6^ in Drive mode, to improve the overtaking of another car.



To have the downshift, I've to put the accelarator pedal all down, the engine go up to over 3K+ turns and there is 1-2 seconds in Turbo Lab.



It's the same in Confort and Sport mode.



It seem as an 80s years turbo!!! (but today I'm not mode old as in the 80s ...)



I've previous experience with similar engines and gears from Audi and the engine power was every at my disposal when requested, in microsecs.



any comments?



(sorry for my english, I'm italian :))
