Emissions testing numbers

Would like a few numbers if possible from other members.

I took my truck through emissions today.... Man I hate that revving crap.

Anyway i realize I have a different turbo then most but in the stock setting with air intake and exhaust my opacity reading was 4.5%. The standard is 40.0% and the max is 60.0% So I am waaaayyyyy under the standard. Anyway was wondering what others were seeing for their opacity %'s.

Mainly I was curious because I run B100 in both my trucks and want to see what a similarly modded truck runs on petroleum diesel.

Thanks

My reading last year was 8%. That was running the DP-Tuner 40hp tow tune on the stock turbo and stock exhaust. My next testing is due in April, so I'll see if I can get a lower number.

BTW here in CO we fail if we go over 35% opacity.

I have had to test mine twice, first time was 2%, last year was 4%. The first test was a joke, I didn't really rev it past 2000rpm so I guess you can say you can pedal the test. Ease the pedal vs. mash it. Anyway, new county I am in now doesn't do emissions on diesels, so no worries here anymore.

Been passing the test with no problems first on 91 7.3 IDI. And later 99. Still glad they got rid of it. Hopefully that will be a trend for other places.
