I agree with shaneski but I'm very far from an expert. Someone correct me if I say something stupid pls.
I would have expected the LTFT to be much more negative at light throttle - yours is steady -0.16% all the way through even at 12% throttle, not sure about that. I expect mine to be lower at light throttle. I watch mine jump around from -10 to 0 depending on throttle % but light throttle usually low LTFT (?) It does jump to 0 quick so maybe that doesn't mean anything. The only time I saw it positive was in +45degC ambient temperatures - really hot weather.
STFT seem awfully high - that's a lot of fuel adjust >40%
and 1.75deg KR at nearly 3000rpm and 69% throttle raises my eyebrow... seems....borderline (?)
For me it's a guess, I'm all theory without mechanic experience. but I think looks consistent with unmetered air entering system.
Meaning check....hose clamps on intake post MAF sensor and pre-turbo.... vacuum lines....what shaneski says. Anything after MAF that can suck in air under vaccum.
I reckon shaneski is on the money...let us know how you go?
