If you don't plan on going beyond stage 1 ecu flash, your probably OK with smic's, at least in cold weather. My RS6 even at stock would heat soak pretty quick in the summer with the stock smic's. With an FMIC, I never have to worry about that with any upgrades at any level in any temperature. That to me out ways everything. And personally, I like the look done right. Everyone thinks my RS6 is a lot newer than it is.
