Hey there - yes that's right, I've been using Steve Howe at Triple H Motorsport for my Revo mapping, mainly because he was recommened by a friend and it literally 5mins from where I work so much easier for me to get to during the week. Whilst I'm sure Dave at PDT also knows his stuff [plus does have a RR] getting through the Tyne Tunnel made it much harder for me to get to.
Also, in the 2 dealings I've had with PDT, I wasn't overly impressed with the serivce; firstly he went out to test the brakes of another member during the time I was paying for to have my car data logged and eventually flashed back to stock... I do accept that I didn't pay for the reflash so not too bothered. The 2nd time I had organised to come and have a Milltek TBE fitted on a Saturday, only to find out on the Friday afternoon that he didn't have time for me.
That said he does have a good knowledge of ECU's so I may pay him a visit for some datalogging on my way back from having a BF TBE fitted next monday.
And yes you were right he just set my car back to stock via the REVO port, not a compelte stock reflash.
