Does anybody have specs on what it does to the engine? Turbo pressures, timings, etc?

BTW, in my experience, $1500 is not a terrible deal for a power increase from 400 to 440 hp, considering it is factory fresh, warranty unnaffected, and no need for aftermarket tinkering.

I am now anticipating delivery of my car 10% more than before
To be precise, the actual HP is 407 and the power upgrade adds 42 HP, so the total is 449 HP.
