I am looking to do a 400rwhp build on my PSD. my currents mods are in sig. I want it to be reliable, and not have to worry about having to crawl under it, or have to crouch under the hood very often. My thought were, stage one single shots, GT38r, VB, and a chip reburn. I am sure there will be more needed to get me to my goal of 400rwhp. What am I missing? Will a VB be sufficent for my trans, or will I need to be looking at a torque converter as well? I will be daily dr ing the truck, not romping on it very much, and I do not want smoke. I realize there will be smoke, but I would really like to avoid it daily driving. What else will need to be done to hit my mark of 400rwhp, being reliable? Truck has 166k on it and am looking to get at MANY more miles out of it, without having to spend large amounts of money repairing.
