Sounds like your goal and the original designer's are 1 and the same. You can make more short-duration power running hot and dirty, but more towards that end of the spectrum takes away from reliability and longevity. Funny thing about the swirl flaps is they have little if any effect on power and removing them to prevent their failure is really disingenuous, with no documented risk except the big fear of "what if" somebody dreamed up floating around in people's minds.
But they do have a strong correlation to DPF longevity and fuel mileage in mixed driving. I wonder how many of the pre-maturely failed DPFs were running around without swirl flaps? My definition of "strong" in this context may be a little different than most. Good luck validating that claim.
