The car, once owned by WilliamsF1 (Ben), details here
Well, after enjoying the vehicle for two months on WA roads I've just had the car serviced. I asked for a dyno power run only to be informed that the car was running so lean and with so much advance in the timing that a proper power run would be dangerous. The car is now booked in for a day of tuning! This scared the shit out of me considering that the car has been driven reasonably hard since I bought it.
Ben (WilliamsF1) assures me that the car was tuned on RON98 (same fuel I'm using) by Jim at CRD and that it should not need retuning.
Below, is the Dyno run that supposedly shows shockingly lean fuel. As I'm not trained in tuning cars, your comments are appreciated. The car seems to run pretty well, so I'm loath to have it retuned unless really necessary.
