Your dealer is correct about the neosocket- Basically its electronic snake oil. The risks involved negate any plausible gain.
As far as performing the reflash yourself- the code reader you sent me the link to is only for pulling codes and viewing data stream info. To get into equipment capable of doing a reflash, youm are looking at a sizable investment. I personally use a unit from EASE Diagnostics- Their Universal ReProgrammer interface II. The unit, along with the necessary battery support equipment, I have invested about $2600.00 not including the new dedicated laptop. Not too feasible for a single user. For access, to say, AC Delco (GMs data provider, the rate is the rate is $55 for 48 hour access. If you haven someone willing to do the procedure for $80, I'd take that deal! The relay is definitely DIY, its just plug it in and go. Hope this was kinda helpful. Doc
