That makes sense, but maybe the intent of my question didn't make it
through. What I'm looking for is a place to start. I'm thinking about
starting with the 'vette hack, but using iron head timing maps. I would
tune from there (hopefully with an EPROM emulator!). There would be a
lot of testing involved. I'll probably be riding around my neighborhood
sitting on a milk crate and tuning the motor. <G>...

That's good to know. Great excuse to buy a G-tech, and not rely on my
hard to calibrate butt-o-meter. I like the phrase "it felt so much
faster" as much as you do... ;)

Thanks!
