No, there is no input for that, or any other inputs for that matter. We've also tried running cars in fourth vs. third and there's almost no difference in the power and torque curves - within 3-4 hp which is within the tolerance changes that occur as the engine heats up from run to run or exhaust fumes accumulate around the cell area if it is not well ventilated.

Not sure on that drop, but it could be from an sudden AFR change right at 5200 - would have to see the AFR chart to determine that. However the drop is so abrupt, and continues quite smoothly, it appears almost as if the full throttle microswitch is not activating, or possibly on edge so that right at 5200, the shift in the engine under load is just enough for the linkage to change the engagement of it, having the tune go to part throttle.
