Just a quick question.... I was going over some mods I have and some things I plan to do in the future with my car.... I was looking through the Modding for Dummies thread and Modding your Evo 100 @ a time and no one seems to have anything about wastegates. Are they not necessary unless your upgrading your turbo? I just remember them making a big difference on the SRT4s so didnt know if it was a waste or not.
