change 850 to v70 d5

since the appearance of the current v70 (which is already some time ago) the desire for a new (volvo) is still moving in me, but please as a diesel. the audio-diesel has been on offer for a long time, but first the new diesel makes the thing worth considering for me. the test values indicate the volvo in terms of consumption with approx. 8 liters. in your forums one reads however from approx. 6 – 6.5 l diesel. who is right now, since works data in the rule nac h are counted below. topic is certainly also the topic chiptuning, since colleagues from me passat with hopa chiptuning drive. must say, compared to the original amazing. problem is only that hopa in the foreseeable time does not build a chip for the 120 kw diesel. the advantage of hopa is that a support point dealer at the place (94315 Straubing) has and also a corresponding tüv report that makes many things easier. maybe someone can answer me to my post and his e Report or communicate your opinion
