If you have your D5 engine "Optimised" does it come with the "Over Boost" or is this something new? I copied the text below from the Volvo Polestar site.

D5 Over Boost
The Polestar Optimisation software for the D5 (68) engine offers an exciting enhancement. Polestar have introduced an “Over boost” function that provides an additional +20nm Torque and +15hp power for up to 20 seconds once the peak power of the engine has been reached. This additional power and torque is over and above the already increased output figures that the Optimisation provides so you get an impressive boost when you need it most. The standard D5 (68) engine produces 235hp and 480nm torque. When this engine is Optimised and is in Over boost mode, the figures are increased to 255hp and 520nm torque.

• Starting from 18w48 the Polestar Optimisation SW for D5 (engine code 68, D4204T23) will be
enhanced with an overboost function.
• Power and Torque will be momentarily* increased with up to +20 Nm torque and +15 Hp over and
above the already increased Optimisation output figures.
• Applicable models :
– MY19: XC60, XC90, S/V90, V90CC D5 (68 engine code)
– MY18: XC60, XC90 D5 (68 engine code)
• Already optimised cars will automatically receive the additional overboost enhancement when the
car receives a SW upgrade via VIDA at the VCC workshop (i.e. Service 2.0).
New Polestar Engineered Optimisation Overboost enhancement (D5)

Very interesting.
Would this apply to the late 2015 V70 D5?

Edit just seen it’s the 2.0 engine

Just to put this into perspective. I do not believe that the Polestar optimisation on my 2012 XC70 D5 has the overboost feature and to be honest I don't know that it really needs more that the basic enhancement that the Polestar rewrite gives. The acceleration is markedly better and I'm not sure what I'd do with more than what it now has!
