I asked the same question you are asking sometime this summer a thread called "bolt-on tuning how much" or something similar. I didn't get a great help from that thread, but there are some interesting points in there. But mostly you will be dealing with the VE tables and getting them spot-on before you do anything. A WBO2 will help out tremendously in that regard. I haven't got too much into the part-throttle enrich and parameters of the like, but I'm in full-time SD now and am running a constant 13.1 AFR as opposed to the 16-17AFR it was running before with just the intake/exhaust mods. I'm still in the very early stages of tuning, and hindered by an inoperable clutch right now, but I can tell you that getting the AFR in the ballpark of where it is supposed to be makes one hell of a difference. As for torque management, I probably better leave that question to someone who has experience in that area. My advice if you can afford it, and you don't already have one, is to buy a wideband o2 (LM1 here but there are other options as well) as it makes getting the AFR correct so much easier, and to go to work on the VE tables. That'll get you started. Good luck to you.
