I have found that some dyno results, peak HP and peak torque, aren't what the car will want for stall on the converter and shift points
My message is on shift RPM is to take it to the track and test different shift RPM, start with the RPM the dyno said was peak HP and then go down 500 RPM and if the car goes quicker try another 500 RPM lower, if it goes slower on the peak RPM shift points than shifting it at or above 500 RPM above peak keep testing to find the best RPM. Once you have it narrowed down between two five hundred RPM shift points try 200 RPM higher or lower to get to the best shift RPM, test, test and test some more
