Default Q: A/F ratio? - 2006 Extreme

Hey guys I want to pick some brains here. I've been told that my car has had the fuel trim tuned to be 11.5 - 12.1 at idle and cruising speeds but it wasn't dyno tuned so my question is how lean will it get at higher rpms if it's 11.5 - 12.1 at idle to 2500rpm? Should it still be in the "safe zone" at higher revving rpms?

Default A/F ratio

It should not be 11.5-12.1 at idle. Those numbers are for WOT. Idle and cruising should be closed loop and 14.7. Your tune at WOT should stay within the 11.5-11.8 all the way to redline.

Yeah it didn't sound right to me either that's why it raised a red flag. I've got a little soot from the exhaust so I'm guessing he meant at WOT but who knows. Ok well at least I'll know what it should be set at then once I get some data logging done and get it tuned again. Thanks Seelye!!
