300 HP Northstar vin 9 version question

This question will be for the old timers I believe.

Years ago, I recall the guru or bbobynski stating that when the Vin 9 came out, the hotter cam caused a lope that owners complained about and GM developed a PCM flash that tamed the lope down to an acceptable level.

Does anyone recall this statement from the guru?

If this is true, I wonder if it is possible to get the original "flash" or firmware WITH the lope, I would prefer to have the lope....
