This mod may help slightly up top but will definitely kill performance off the line. Especially in AT where wot is needed to get moving quick. Lift the break and go wot, you will be left dead in the water until you slowly climb to 2k rpms when the car will finally get moving. In NA configurations it needs to scavenge a bit for air to get combustion going. Velocity vs volume. If you have already done this mod and have experienced this problem just cover the modded snorkel inlet until you get the same surface area as before. I found that my Frs actually responds better with slightly less surface area than the original stock inlet. I am running E85 on the oft stage 2 tune.
