No, not really. I just don't see the point of dropping coin on a dyno run if your goal is to get numbers as inflated as possible. "What dyno can I run on that will read as high as possible," is sort of a crazy question to ask.
If you're doing dyno runs you have to understand that the numbers you get are a product of the type of dyno, software correction for temperature, air pressure, altitude, humidity, drive ratio of the gear you are running, etc etc etc. You can muck around with a lot of stuff to tweak numbers, if that's your thing. But why would that be your thing? If you're starting to dyno your car you want to baseline in as controlled an environment as you can so that next time you come in after you've slapped a CAI and a catback on your ride, you can compare your gains to your own car under similar conditions. It doesn't matter if your baseline was 210, 225, or 240 HP, what matters is the percentage increase in power you see from your baseline to your modded run.
Picking a place to start doing dyno tuning, things like the reputation and the experience should matter more than the dyno they use (unless you're trying to find a shop with the same dyno you've used before for previous tunings or baselines). The 210 HP Mustang dynoed stock Mazdaspeed3 and the 240HP Dynojet dynoed stock Mazdaspeed3 are probably capable of running within a 1/10th of each other on any given track, but there's a 15% difference in reported HP because of the dyno used. The reported number is meaningless on its own.
