Yea im gonna go with the front plog, i would drop to a 3.4 but i hear guys do that with relatively stock GTPS and just blow nothing but KR with that. I also heard that the supporting mods ZZP says you need for the 3.4 is wrong and you need WAY more supporting mods for it, so for now i wanna do it very last but part of me wants to buy it now lol
