Hey guys I finally received info back from HRT Hiop, gains are not that impressive. Stock the 125i (here in Australia) comes 160kw and 170Nm, with the ecu tune it is upgraded to 170kw and 285Nm torque. I have compared DMS, Powerchip and now HRT ecu tunes, DMS gives the best result. After DMS tune, 176kw and 294Nm but it is also the most expensive. BTW HRT tune is $1645 Aussie Dollar.
