250psi in 60 sec in leak down. Fuel pump is new last year. Only 130k miles on it. I don’t know what else to check. My thoughts are going towards the tune because it’s the only thing I don’t know enough about to check on. But I do want to check it to make sure. I’m so confused and running out of money fast.
