In my opinion, if you can't afford the dyno tune/road tweak, a dyno tune is still better then a road tune. The predictability and repeatability of a dyno (not to mention that you won't run the risk of speeding on public roads) is much safer for your car. The 'realness' you gain is really negligable when you consider the repeatability that you gain from dyno runs. Your radiator and intercooler get as much air as they need (esp. considering dyno pulls are only for a few seconds) and you really need not worry about the lack of airflow comprimising your tune. There is a heatsoak issue between runs, but that never occurs during the runs.

Repeatability is one of the main tennants of the scientific and engineering methods. Running on unpredictable roads will give you unpredictable results. Ed claims to have a predictable road, so maybe you'll be okay, but I can't see it as really being any sort of advantage over a dyno. I bet you'll probably save $300 by going to Ed, so maybe that is a good reason to choose him.

I know we've had tons of PM conversations over this, so there isn't any need to re-hash this. I guess we'll just stop it here. Also, I get the feeling you are thinking I'm flaming you, I'm not. I'm simply disagreeing. If it seems like flaming, let me assure you that it isn't. And look, we didn't turn this thread into a 'bash ed' fest. You mentioned you were going to get a tune from him, and everyone here is concerned for your car and is trying to let you know how dangerous this may be. We're not here to bash Ed (I doubt he's even reading this), its more a chance to impart some of the wisdom a lot of us have picked up after being on these boards for years. If you want to ignore it, thats really no skin off our teeth.

And FWIW, I have certainly seen Ed put down some good, safe numbers, so I do wish nothing but good luck to you, even if I disagree.
