Around 62k miles on the car and is pretty well maintained: recently did the differentials and transmission fluid change and regularly do oil every 5k miles. This has happened before like twice but I never really thought much of it cause it goes away but it happened again and im starting to worry.
- Another thing to note is that my car eats oil. Don't know if its cause of the tune or anything (or just cause its an n55) but about every 2 to 3k miles it tells me to add a quart. Had that warning pop up last week but put did an oil change about 2k miles ago adding 5 quarts. Seems a little fishy to me but I thought it was normal given the n55 loves oil and given the fact that im tuned it didn't make me think much of it.
I'm no expert in log reading but I see my fuel pump dipping: https://www.bootmod3.net/log?id=5ff2...0b431a1b66c45b

Go stock plugs, having the same issue. I'm switching my ngks and pr coils back to stock and back to ots 93. I went so many different ways about it and this is like the second to last option I have
