If you do decide to tune, I used Ryan Hogan. Pretty happy with what he has done with my 99. I have probably one more data log to send and most likely he will be sending me my last tune this weekend.

I have only had my XJ for almost 2 years and have put a rebuilt motor in but I have never felt it accelerate as smooth as it does now. We bumped up to 92 octane, right around 15 mpg street and 20 mpg highway.

Very happy with what he has done.
