I was curious if anyone here is running or know people running water/meth injection on the Z32? I am getting my ECU back from JTW next week with just the basic tune. All I have done is a pop charger, 3 in downpipes, 3 in z1 pg exhaust with test pipes, and of course the tune and boost jets. I am planning on getting bigger intercoolers soon as well. Would meth/water injection make sense? Do you need a tune for the mixture? Companies like snow preformance claim nice gains from their 450 dollar system.
