djqc Member 291 Member For: 13y 6m 15d Posted 03/02/13 01:23 AM Share Posted 03/02/13 01:23 AM I've recently had my car retuned, and I was told its around 12.8It is making more power than before, but the oil temp is up about ~10*. This leads me to believe that the car is running leaner. Is it safe?My mod list is in the sig.

With more boost charge temps will go up but by the looks you have the mods to support so that shouldn't be a big deal your engine temps will be going up because it is running lean, can only assume its on 98?On pump most aim for about 12.0 abit either side isn't a big deal though. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/83856-ideal-afr-for-400kw/#findComment-1357953 Share on other sites More sharing options...
djqc Member 291 Member For: 13y 6m 15d Posted 03/02/13 08:16 AM Author Share Posted 03/02/13 08:16 AM On 98. The car had more boost in it before.Some boost was taken out, and timing added in the current tune, and the result is higher oil temp. I'm also led to believe that the tune before had a richer afr than 12.8 Link to comment https://www.fordxr6turbo.com/forum/topic/83856-ideal-afr-for-400kw/#findComment-1357959 Share on other sites More sharing options...

djqc Member 291 Member For: 13y 6m 15d Posted 03/02/13 08:33 AM Author Share Posted 03/02/13 08:33 AM Also very expensive. Is the ideal afr in the mid 11s, when up around 18 pound?How lean is 12.8@18lb? Is it really lean, or a touch lean?
