Hello
I’ve recently moved from Texas where we did not have emissions testing on diesels and I had plans to do some mild modding.
DPF/ DEF delete
EGR delete
Exhaust with a high flow cat and no muffler
Malone stage 1 at the least.
Trouble is I know have to conform to the emissions requirements of the Front Range in terms of opacity % which can not exceed 35% in their tiered 30-40, 40-50, and 50-60 mph tests on a dyno.
With the car all original 55k miles I passed 0% all around.
Is anyone experienced in passing these tests with any kind of emissions equipment mods/ removals?
Cheers!
