In case it wasn't obvious, I was being tongue and cheek with that response. When FoxMustangLvr curtly implied that neither your MS or his PiMP (re badged megasquirt) cared about smog, it was more my pointing out the obvious. The aforementioned systems are great for guys that can justify their purchase....but for your average bolt on, near stock Joe that just like to rip parts of their car and doesn't want to trip ECU codes, its hardly a practical purchase.@Gearbanger101
The 1000 dollar software system was to do what the factory ecu couldn't/wouldn't. Not much point running an egr with turbo.. and not dumb as implied..Stock engine and injection is a different story.
A little off topic, but: the whole thing about the smog equipement pumping fresh air into the convertor to reduce emissions, that just sounds like the contaminants are being diluted, not reduced. It's like saying river flows 1000 gallons of water, and 50% of it is contaminated. So, let's pump 1000 gallons of fresh water in and we can say it's only 25% contaminated.
Is this really how this works?

Perhaps, but these are also area's vastly underpopulated, or heavily populated by newer, emissions compliant vehicles.....not busted out old hot rods like we're driving. Just because an area doesn't have a smog standard to meet, doesn't mean everyone immediately runs out to the driveway with a hack saw and cuts their converters off.As far as clean air goes, there are still hundreds if not thousands of area's where there are no smog requirements and they have plenty of clean air.
And @gearbanger101 I alternate DD duties between my stock fox w/o emissions and my intake/tune/exhaust coyote and I would bet a ham sandwich the fox would edge out the coyote in city driving. On the highway, the fox wins by a couple MPG. I can't prove it with stats ( I can start logging if I need to) but I can tell you that any RPM over 2k and the coyote drinks fuel. The fox hums along in the mid twenties.
Guess it all depends on how you drive it. I don't generally consider edging out the fuel mileage of a car weighing 600-700lbs more, that's making double the horsepower, while producing a fraction of the emmisions...all while promoting better drivability an enormous victory, but like you said, its all in the way you slice it.
