Dan, Currently the most effective shift points I have found is ~6250 from 1st to 2nd and ~6000 from 2nd to 3rd. Interestingly, I took my dyno test data and did I curve fit to the power data, so that I had a fourth degree polynomial which "decsribes" our power curve. I then ran a simulated "pass" creating a graph of power vs. speed, then visually maximumized the area under the chart by altering the simulated shift points. My results yielded that the following shift points as optimum to stay in the engine's peak power band. 6300, 6050, 5900, 5800. In application, with a stock 2.0L, I have found that you dont want to make the shift to fourth, as the time it take to shift is greater than going ahead and "riding the gear to the finish".

Yet another way I can improve my awfull times! I know I have no power way up in the powerband, but I didnt know where to shift. So I've been shifting at roughly 5500-6000 depending on how much power I feel I have left. I will try the shifting points you say. Makes me wish I had a shift light, hehe. Dan
