I'm running a stock setup right now except for a KnN filter(does that even count as a mod) I bought a datalogger and have been running it on the car for a little while now. And I noticed that all my fuel trims are set to 139% at H M and L. Is this normal or bad? What kind of fuel trims do other people get with stock fuel systems?

If it's bad what can I do to fix it I don't have an AFC but will get one if this is something I should really be concerned about. I did replace the injectors once but got supposed stock replacements they have blue tops on them if that will help identify them.
