Re: XR8 BA Manual FUEL SUCKS
BAs, Ford and most cars come out of the factory running very rich. This is a warranty friendly thing as if they are too lean, they burn... and also cars are made for less of the performance aspect than the daily driver aspect. So they tend to be a bit conservative and its always safer to run richer than leaner within reason.
Also, each engine is not individually tuned on the line - and each engine IS different. So some engines will run leaner than others....
I found that with mine. My AFRs were around 11 when it was first dynod. Which was about as bad as they had seen. I got a Unichip and it went up to around 12. Since I had the exhaust mods the fuel efficiency has improved again.
I would recommend getting it dynod to see where its at, if you havent already. And then think about some sort of chip to help with that. Either that or the Boss Edit, which I assume would also fix that problem.....
It would get better over time too, as you run it in....
