Adjustable cam timing pulley - optimizing for better FE

Well, my adjustable cam timing pulley for the Paseo will be here within a few days now. So, I figured I'd start some discussion around it and give some background on the engine it is going into. First off, here is the pulley.




The engine it is going onto is a DOHC, but the two cam are geared together. So, they are not adjustable independent of each other. So, if you advance the pulley, the intake and exhaust cams are both advanced the same amount.

Here is a picture of the cams. The exhaust cam is on the top and that is the cam that the pulley is attached to.





From the little I've read, advancing the cam timing helps low end. However, I was thinking that I might be able to get a bit of the Prius/Atkinson like action going on if I am able to retard it enough. Ideas?
