I honestly don't understand the question there???
Generally, the hypertechs increase the Ignition Timing.
You can do this yourself for free by turning the distributor

It is possible that the hypertech modifies the fuel metering as well, but how would you know that the hypertech values are what you need in your car???
Pretty much a waste of money/time... If you want to get into the ecu settings/tuning there are better ways to do it....
