Idle LTFT on stock coyote engine, 10 at left and 6 at right, normal ???

[Duntov Supercharged]

Hi everybody
I know HTP not support this engine for now, but i need to know if my friend have a problem with his car or if it's normal !?
HTP is capable of scan, so, i done

+/-5 LTFT is currently normal, but it's a bit higher here
AND car is completly stock (only mod is a borla catback)

Car is a Ford Mustang 2011 (but HPT say 2010, dont care)
The car is only 15k miles
The owner can't know if something was done on his car (or, without be able to download his tune, i can't too)

Idea ?

That is more correction than I like to see, but unless it is throwing codes, I wouldn't be too concerned with it.
