With 4.56 gears and no HPP3 what does the skip shift do?

With 4.46 gears AND HPP3, does it work OK???

The actual gears are 4.10's in all cases.

With no HPP3 (stock programming for 3.42 gears) the skip shift light acts "normal" based on the uncorrected speedometer, oblivious to actual speed.

With HPP3 programming for 4.56 gears the skip shift light comes on in second gear, again oblivious to actual speed. This would indicate to me that the parameters for CAGS activation ... speed, rpm, temperature and %throttle are being met.

My conclusion: The CAGS section of the computer is getting the HPP altered speed input.
