UpRev full tuning capabitliy??

[pg6speed]

I'm new to the need for tuning the ecu of cars as my past cars have not had ecu's in them so I called up UpRev for some info. From reading this forum I was under the impression that tuning capabilities were basically limited to A/F corrections.
I spoke with Richard at Uprev about getting my car tuned there soon and questioned him about what all they can do (correct A/F ratios and rev limiter, etc). His reply was that they are not limited to A/F and rev limit or valet modes etc, but have Full tuning capability of this ecu. Is this news to anyone or am I miss understanding something. Does Uprev have the ability to fully tune this car at their shop that they havent released to other authorized Uprev tuners??
