So I have had my OW fost for about 6 weeks and I just installed my fmic to add to my unleashed tune, exhaust and green filter. Other then a downpipe or going big turbo, are there any other worthwhile performance upgrades? Not some BS, I mean proven performance upgrades? I have searched and searched and I am pretty sure the answer is no, but I want to be positive before I switch my focus (lol) to cosmetics.
