I looked at few things and got the idea that the slower you drive the better gas mileage you get.

I am interested improving the cars efficiency with similar driving as I do now. I really like Atkinson Cycle engine, I also would like to improve some of the things in drive train so when it's all done anybody can drive it and get similar results without making the car less reliable.

That's the idea I got

Personally, I've found the gliding, or coasting to be really effective. Pump up your tires to the max sidewall pressure, accelerate slowly, don't go over the speed limit, and coast to a stop (ideally) without brakes.

Good mileage is a very relative term... What are you actually getting with it?

I've see too many tire blow outs, premature tire wear, rougher ride and suspension problems with over inflated tires. I don't know about you, but 1mpg extra is not worth all that hassle to me personally.

I get about 22mpg in the city and 29mpg on the highway, I'd like to see 40mpg on the highway.

You might be right about that. Personally, my tires' "max" tire pressure is only 40 psi, which is only about 5-6 psi over the recommended pressure. I don't know how much additional MPG that gets me, but I do seem to be able to coast longer than before. And I don't think I'll have too many of the problems you described. I can't imagine running 50+ psi like some folks do, but I think the game here is the combined effects of many small modifications that can add up to a significant difference.

did my second mod, high flow exhaust, lost 2mpg

Uh oh! You lost 2 mpg? Maybe you need that additional backpressure.

That's what it is I guess.
