especially on the island here! i felt out of place when the truck had the old ip and smoked everywhere. California is usually the test bed for these kinds of laws and with them not emissions testing 1998 and older diesels, the more people that go around choking out people on the streets, the more they are inclined to change the testing year. Soon we all will have DPF units on the truck and cats. Friggin crazy but its the posts like this that scare me and make me wonder why you want to "roll coal." Thankfully he thinks its turning up injectors so i think we are safe. This is the wrong forum for rolling coal and threads always end up like this. I say we stop telling them to get a pyro and encourage the stupidity to kill this crap off.
