Hi there, this chip is for a Vanos 320 and to be honest, fuel consumption is much better than it was before. For all info on the chip, you could try asking Mark D'Sylva as he made this chip for the 320.
Its been a great chip in my car for the last few yrs. Only reason that I am selling is that I have a 325 engine in my car now so my 320 chip won't work. I just did put a Mark D chip on it today and it works fantastic, just like the 320 did.
