So I'm having a few issues with the ute. . . . RDP had the ute for around 3 weeks to trouble shoot what was going on but came up with no conclusion. I can't thank them enough for persevering and looking after me the best they could. What seems to happen is the car leans out worse and worse after every consecutive back to back run. Just about every sensor was replaced, throttle bodies, fuel rail, injectors, surge tank, hours and hours of data logging with no fault coming up. It makes good power through the range, and doesn't lean out on a power run but when it's running a bit warmer after back to backs it goes out of control but comes back to good afr's by limiter. . . Open to suggestions
