Yea, I read the article but I still wonder how DEF delete kits are different than what he did.
Guys that make a lot of money probably don't want want to mess around with something that MIGHT work.
Things to do, places to be and people to meet. You don't get much work done with a chainsaw that's got all these enviro gizmos that could go wrong at any second, for example. And you don't get paid if your truck breaks, and you can't get to where you HAVE to be.
Unless you're a government guy. "Hey, my USF&G truck broke. I still get paid, BY YOU, bosco." "Hey, my brand-new junk chainsaw's sensors messed up again, it won't start and I can't use it to get work done. I still get paid, BY YOU, bosco."
