[unstable bob gable]

I'm on a quest to ring max MPGs outa my Sexalier, and I've noticed that HPtuners supports my car. I would think that some tuning would help a lot, as the car has the typical GM "run rich" format. Only prolly is, I'm less than even a noob to doing my own tuning, and I don't know about shelling out the bux for HP + a laptop to do the work. I know Bill [foff] doesn't do outside tuning anymore, so is there anybody else out there doing it? I'd rather pay someone else for their expertise vs shelling out big bux for something I may use to f' up the car...
