POWER SHIFT!!! Ah, wait, that's retarted. At least if you want your tranny to live long. If you're pretty good at it, why do you want tips? I guess the best thing I could say is learn to balance the clutch and gas in first to that you aren't moving while holding the engine at a higher rev. Find a good engine speed at which you can drop the clutch and hit the gas without too much spin or the engine bogging down. Each car has a little different optimum speed, depending on state of tune, traction, etc. I find my car launches best at 2500 w/o bogging and a tiny little chirp. I haven't found many who take me right off the line (then again most people I race have auto's it seems...)
