Default LTFT question?

When scanning a friend's truck, his LTFTs were all read on the display and in the histogram the cells were all read and it was adding like 23-25 units. Is this signs of an air leak somewhere? Or maybe a bad O2 sensor? Also, his IAT temp was a little high.

Could be a vacuum leak or bad O2. What's the pressure at the rail?
Are the stock injectors?

Is it throwing lean codes yet?

I haven't checked the pressure. They are stock injectors and I haven't checked of rnay codes yet. It scanned fine the last time with no changes to anything other than the brakes.
