I have this TCU flash, thanks to Jerry he is always the best.
combined it with his ECU, the car shift now at 6500 rpm not at 6200,
also you have a full manual M mode, torque converter jerk gone 90%.
Before if you spin tires at wot it shift earlier at 5700-5900, now it wont shift till 6500.
i will post video about the shifting.
