Hi,
I have the V70-new model with 140 hp (103kw). 2.4L, 20V, aut.
I was wondering if there really is any difference between my engine B5244S2
and the more powered B4452S with 170 hp. As I understand it is the ECU that
is programmed differently, but same engine.
My theory is to software upgrade the S2 so it would deliver 170 hp or more..

Thanks in advance

Have a look at the two topics below from the Volvo Owners Club V70 Forum.
They might point you in the right direction:

RICA or superchips etc all do a chip for the 140 engine which takes to
180bhp. Check them out.
