tuning shift points
1. I kept the stock 6000 rpm shift points
2. modify the MPH
3. Note that if you add a underdrive pulley or add something that ramps up your RPMs quicker than normal you'll be lowering the MPH shift points not adding to them (at least I did)
Be careful you dont over rev the engine and float a valve or something (not good)
6000 is really where you want the pcm to shift because by the time it does you're already at 6200. Note, Tachs are slow on f-bodies so dont rely on them, rely on autotap(or other diag.) data.
