Easy/cheap ways to improve low end torque?

I believe it's Julian Edgar over at InsightCentral who is running a custom ECU in his Insight. He's a very experienced tuner, and makes claims that he has seen healthy improvements in economy by running a lot more EGR.

Now that I have this untampered Honda and a little more knowledge and experience I can do some more testing. But I understand your theory. From what I've read egr is just to decrease compression temperature down to reduce Nox or something.

EGR does end up decreasing the dynamic compression ratio, which is indeed different from the static compression ratio usually advertised. When it comes to keeping the engine cleaner after an EGR delete, it's been more of an issue with Diesels and some of the earlier direct-injection gassers because they tend to have a higher particulate matter emission, plus the fuel injected at the intake manifold in a conventional gasser tends to dillute oily vapors aspirated from the crankcase through the PCV, preventing the carbon buildups to accumulate at the intake manifold.

The op was askimg about torque. You can increase torque by decreasing pumping loses. Free flowing intake and exhaust. Back to basics. I think max fuel economy is at the same place as max torque.
