another potential gain is that with an identical engine with a turbo, you can run along with a numerically lower FDR to drop cruise RPM and lower vacuum losses.
Robert, could you explain what FDR is, I'm sort of a new to the technical aspects of FE, google seems to think it is flight data recorder.

I just had that trans out to fix the torque convertor issue, I think I'm going to leave it in there for a while. I like your idea about the shift points and changing programming through flash tuning is something I'm interested in, as well may be necessary before I'm done. This is my first Ford since I was teenager, I'm really not familiar with their PCM's or how well they deal with boost. Know of any good diy programmers?

On another note, what do you guys think about asymmetrical turbo charging or using one turbo on one bank of cylinders that feeds the whole engine. saab did this for a few years on a v6 with not much boost or power increase but supposedly made the torque curve much larger. there are a few very interesting diy threads on this, I'll see if I can dig them up later.
