In my experience
ED = polesmoker that charges me $600 for a "full tune" that was done in the whole of 1 and 1/2 hrs . the dyno printout showed it was only the 3rd run on the dyno. I was silly enough to trust him and pay up front before I drove the car(BTW No receipt, cash just went straight into his pocket) . I jumped in the car took it for a quick fang , knock up to 110 , yay . Rang said poovta up he says can't fix it today and to meet him at the dyno first thing in the morning. So I show up at agreed time, he shows up an hour or so later with another customer and says he'll fix'er up when he's finished with other bloke. after waiting 3hrs he comes over tells me he's out of dyno time and he'll have to road tune it. we go for a quick drive all he does is take 3 degrees out of the whole top end of the map, leaving me with a car that feels not much better than it was before. :end rant:
If it was you that got ripped like that you wouldn't be to happy either.
