This will be interesting to see the responses on this. Some people think that dyno time should be bought in hours and that is crazy. A proper tuner should be able to get you in and out in a short period of time by starting with a map that is close and then fine tuning it for your build. If the tuner is incompetent then I can see why you would end up being there for a while.
A Stage 1 should only take a few runs, maybe an hour. A performance build will take 2.5-3 hours if you want all the performance you paid for.
If your tuner doesn't know what he is doing, he will charge you a flat rate, dump a canned map, run it once, fatten the fuel, run it again, print you a sheet, shout "next" and tell you "that's as good as it gets". If that's what your tuner is telling you, you have left HP and Torque on the table.
A flat rate tuner is looking for quantity, not quality.
