I totally agree with that. Deleting going forward will be driven black market behind closed doors. Personally i feel like it would be better to allow the professional tuners to make clean safe tunes, instead of getting a bunch of cranked up smoke tunes from some guy in his basement but what do i know. also, diesels make up what, maybe 5-10% of the vehicles on the road? an maybe, being highly optimistic, 10% of them are deleted. so on the high end.... 1% of the vehicles on the road are deleted. i just dont see how theres not bigger issues to address....
Sorry I missed this and am replying on a belated basis but I have a comment on why the gummament is going after diesel tuning. It is all to do with rolling coal.
Suppose you are an average citizen and don't care much about cars in general as long as they get you to where you are going. While driving down the street you come across a guy in his diesel truck that just loves to pull up along side other cars, particularly hybrids and pure electrics, or bicycles or pedestrians and once he has them in his sights he floors it, blotting out the sky. Now as an otherwise unconcerned person what are you going to think?
Of course you will think, "There aught to be a law." Of course there is a law. There has been a law for a long time. It just hasn't been enforced.
Now suppose you are an EPA administrator. The main thing you want is job security and an upward career path. You sit at your desk all day thinking about how you can improve your situation. Looking out your window on the streets below you notice a cloud of black filling a street. Being a bureaucrat you don't know what is going on but you think that if there is something in the air, you can regulate it, even if it is CO2 from lungs or methane from cow farts. So you call up one of the technical people in the basement and ask them what it could possibly be that is "polluting" the air. They say it is people with non-stock tuning on their trucks.
Well what would any self respecting/promoting bureaucrat do? Of course he would see this as an opportunity to go in front of a camera and proclaim how needed he is because he is going to stop all of this polluting. To give some credence to his breast beating he has to have something to show so he picks a few businesses in the market of selling tuning and hammer's them. It doesn't matter who they are or what they are doing. All that matters is that they are in the business and that they are easy targets.
So some of the best, most responsible people get big fines. The average guy on the street who knows nothing about the real deal but has seen people rolling coal thinks that the gummament is actually doing something good for a change and is happy. Politicians get behind it all because why wouldn't they? So the EPA gets some new money and power. The bureaucrat gets a raise and a post higher up the ladder.
Everybody feels good, except those of us who really know the story. However, nobody cares about us because after all there are hardly any of us compared to the masses of ignorant voters.
