I have been hear some rattle noise from the front when I accelerate at around 60% open Throttle from 2.5k to 4k RPM. I'm running the MAP calibration for Fujita Short Ram Intake. I return my car back to stock calibration and the rattle noise is gone. I don't have any datalog yet because I'm not sure is it safe to drive my car with that unknown rattle noise. Anyone know what might cause the problem?

maybe your hearing bad knock

how can i fix the problem?

datalog. see what ur a/f ratio is check your timing reduce it if your a/f ratios are ok.
