Relying on a fail-safe isn't a good idea.
You probably can't reduce the output of the burner, so you need to get more flow. You said the problem exists with a clean/new filter? Turn on just the fan and go around the house make sure all the vents are open and see if there are any vents that are not producing a solid stream. For the vents not blowing well, look on the ductwork leading to that vent and make sure it's not closed. This process is called "balancing" but it could be a prior owner wanted to save on heating and closed some dampers, screwing up the balance.
Another possibility is that the blower setting is set on low. You want to find that setting and crank it up. On some older systems it's a jumper, and newer systems it's a setting. That latter type, you'll need the manual because, like all these computer controls, it's probably "hold this, wait for it to blink, tap that until you see the full moon, then you can "easily" select low, medium and high...one blink low, two blinks medium, three blinks high" that kind of thing.
