I think might depend on how much more you want to put into it I’m on lowest tune and for 35’s it does exceptionally well but only got 600miles on the turbo so far just wanted to see if there were any obstacles to watch out for !From everything I've read about all the turbo kits, there not worth the money for the minimal gain they achieve ! I'm still waiting for feedback from a guy with one from Evo to see what theirs does.
