Not that I'm going to run it or anything but what's the skinny on the MP8? One of the things they state is how the MP8 is one of the only stackable products and you can stack it with the 5x. According to TS, the 5x is good for 150hp, so what would stacking it with the MP8 accomplish? Does it address the tranny as well? Also, what benefit is there stacking it with another product?
