i hope you guys realize its a direct copy chip. it probably is a watterheur chip or one of the other tuners. so its the exact same software, its NOT too good to be true. There are a ton in the bmw market for about $35 and i've used them and i honestly could not tell a diference betwen $200 chip and $35 one (b/c they are exact same chip). hope you guys learned something new today :)
