It is a few decades back since I used an FE2, however from the start of my photography in 1977 the only film I put through my cameras, including a range of Olympus, Nikons and Canons, was Kodachrome 200. And the FE2 never flinched with the exposure. In essence, you should follow the meter's recommendation, but be aware of subjects that are backlit, in strong shadow or have a mixture of high and low (dark and bright) tones that could potentially confuse the meter toward over- or underexposure.
