Hello dear Volvo community! I intend to install a TUNINGBOX for my new V70 D5 185PS MJ 07. Now to my questions: -from when (kilometer power) it is advisable to install it (though hardly, as long as the engine has not yet been driven)? -which is recommended, the one from MR (1199,-€ incl. sports air filter), or the one from TUNINGBOX (550,-€) The one or other has certainly experience with the above mentioned manufacturers. Thank you already in advance!
