Yeah, I'm with Grip on this one. I am not sure why you think you need to stack. I am a supercharger pulley guy. I don't care for crank pulleys. I would run the code 3, cold air intake, and a tune for now. Now if you are going with some modified manifolds, then you might look at more boost, more fuel. But, I would try the simple set up 1st, and go from there. That is guaranteed low 12's.... 11's with spray...maybe. But to be consistent you would definitely have to look at manifolds, maybe injectors, and certainly a 55 pump. I am not sure if you meant you already have the 55 pump/ regulator kit or not, but once you get into more boost, like a 62mm supercharger pulley or a 185 crank pulley, you will need more fuel for sure, and probably more injector as well. A lot of ways to get there. Each have taken their own path. I'm just a s/c pulley guy, others have their ways...good luck...happy modding... I truck for a seed company, so we get down your way a lot....
