Great results from PCM for Less tuning . . .

[tomp]

So Alvin, maybe you are the one we need here to be able to answer questions? There are some very knowledgable members here and expect a technically inclined answer when ones due.

Please explain to us how this "personal" tuning is accomplished/accurate when they are done in-house and not on a track or dyno? Where the initial maps created at least in this fashion? This would be an acceptable approach, providing they are down-tuned to allow for variances in weight, wind, towing etc.

We were not getting the answers we were looking for, thus I am assuming is the reason you posted. Please explain the above. Thanks!
