Nother update. I'm now legal smile I failed my first smog try quite badly. NOx was 9.x and only 2 was allowed. I added an EGR system and as of today I smog-legal and registered again. .98 on NOx this time smile Also, they didn't bat an eye at my 37" tires either. They did have to double-chock the front tires though to keep it from launching off the rollers when they started the test. I've heard stories of requiring stock sized tires for the smog dyno...
