in terms of using dynos, I agree that the actual numbers really are pretty worthless. However, they are great for tuning a car to make sure you are getting the most out of it.
In terms of determining if your mods are doing anything, you really need to just stick with the same dyno and keep going back. Find a local one, do a baseline run, do some mods, do a pull, do some mods, etc. This will give you an accurate reading of how much your mods are actually doing for your car since it is the same one every time; i.e. you've eliminated the measurement variable and all that is left is your car.
