I understand you're running premium gas now, but what about before? Specifically I'm wondering about the '98 540i manual which states the requirement or recommendation of premium gas (with the stock chip). In other words, the car may already be tuned to high octane fuel.. and a modified chip for this series BMW wont help as much as for the older generations. ?
: 3. I used to average 21.5 MPG (based on OBC)and so far with the JC chip I'm getting 23+. My driving is mostly highway.
