Ok I want to get the most I can out of my stock injectors. I have a #0 plate new clutch a boost elbow any looking at intakes. I do tow so egts are a issue. I want to do 4gsk's in the near future. How much would 191 dv's give me? also looking at a hx 40 that would give me alittle more air to help clear up the fuel. Any thoughts??
