K-pro stock and stock-tuned calibrations

I've posted this on CRSX but didn't get all the answers I needed. In K-pro, what is the difference between the K20a2-rsx-stock and the K20a2-rsx-stock-tuned calibrations other than the increased rev limiter and the drop in vtec engagement at 4300 rpm? I've read this somewhere but I just can't find it again despite searching.

Also for the regular reflash the vtec is lowered to 5200rpm but in K-pro the K20a2-rsx-coldair calibration is set at 4300rpm. Anyone know why?

The K20a2-rsx-stock is the stock calibration. The K20a2-rsx-stock-tuned calibration is a dyno tuned calibration for a stock engine. The VTEC point was higher in the reflash because at the time the reflash did not have a VTEC window like KPro.

To the poster:

It's worth noting that if hondata had *hard* set the vtec poing at 4300 without a window in the reflash, when you got to 4300 at part throttle, the car would likely stumble and drive rough. That is what happens when you hit vtec at part throttle in the wrong place.

Thanks for the response guys. I know there is a vtec window now on the reflash too but I'm assuming this window stays at 5200-5800rpm as compared to 4300-5800rpm for Kpro. I haven't gotten any mods yet other than a Hondata IMG and Kpro so any little bit of power gain helps. BTW, I'm really loving Kpro!!! Thanks again.
