Currently I am running 3 6025's on my 90 with couple of modded maxi jets. I am thinking of getting some 2 6055's since they are controllable and then taking the maxijets and 1 of the 6025's out. I saw that now there are some new things coming out as far as the stream 2. What is the difference between those and the controllable 6055? Should I wait for the new ones?
