We've all heard from forums and numerous outlets that deleting the DPF and SCR on your L5P is the way to go. What we have never seen is data or tests backing up these claims. It always seems to be hearsay that fuels the debate over whether to delete your emissions-intact truck. We like to put these tales to the test to figure out for ourselves what the truth behind them is. What should you really do with your factory emissions system when it comes to what's best for you and your truck?
