Alright, I currently have a Aurora 3000(59/65/.85AR) turbo with 4" downpipe which flows 65lbs/min. It spools quick and does great in the hills of kentucky, but it seems like it dont pull hard after about 55to 65mph. the turbo builds about 47psi too quick and I need something to have a little more top end. I was thinking of a Cheetah Hx35/40 stage II Hybrid. I've seen several people pull around 450hp with them, but then I was also thinking about the 62/65/12. What would all of you think about my setup and what would work best.
