225hp at 35mph as compared to 110hp at 35mph is such an enormous change!!! Am I reading this right?
Do you expect the drive components to hold up with this change?

Giday John, Yes the dyno charts show the difference that the QC makes to the way the box does the changes. The increase is in the torque that is produced by the torque converter multiplying the torque due to the difference in the speed between the engine driven impeller and the gearbox held turbine. When we get a speed difference between these two components we get a torque multiplication, the same as we get during a stall test.
This is how I explained it on the " New Shift Kit Developed" thread;

We wouldn't normally get this as the engine power is turned down, so the torque produced is less.
The QC just removes the TCUs "softening" controls that rob us of good fast changes, lets the box change gears the way the gearbox manufactures intended.
Cheers mate, keep the tyres round.
Harvey.
