Very high long term fuel trims

TheBoomSpoon

Here is a log from a quick WOT throttle in 3rd gear from about 52mph to 82mph. Mine is the 7AT, the car really runs well, feels great just concerned about these lean codes. I think the tuner has it rich because it leans out so much on the top end so from my novice opnion it seems to need to be richer so it can lean out safely but it appears to just be doing too much on the trim. Anyway, attached are the is a CSV log of that run, I left the Fuel map, fuel compensation and MAF tables open so the tracer values would be included in the log.

Be aware I'm not changing anything at this point, just simply trying to make some sense and determine if I'm at any risk running it in this configuration.

These are the engine related modifications:

AAM true dual exhaust 2.5
AAM Cold-air Intakes R-Line (2.75)
Motordyne M370 manifold
AAM VQDE35 test pipes
Z1 headers


thanks for any input. Rename the attached file with .CSV then open.
