i bought a chip for my 92 325i and the guy said that he had two ways of maping the chip. And i dont know wish one to chose, i Really dont understand what low end and top end is? this is his reply message:
I have two choices for the 403 chip, aggressive at the top end or the low end?
Let me know, before I send your chip out, I normally send out my top end chip, unless asked otherwise.
So i have to give him a answer quick, so i need your guy's help!
