Enrichment seems to be a myth. Of my cars only the Skyline does enrichment at WOT. It's been posted time and time again, but I wonder how many cars actually do it?
Nowadays, I accelerate at WOT and shift at around peak torque. In low boost turbo cars, I believe shifting at peak torque is the way to go.
I don't think a SG/UG is of much use. You can set it to 'fast' refresh rate, but it's really no faster than my factory MPG display. The only plus side is you can calibrate SG/UG to your driving so it's slightly more accurate (potentially). Normal drivers find Fiat's OEM instrumentation to be optimistic, but (possibly because I glide a LOT) I've found it pesimistic on occasion. Unless you want the other OBD based features, I wouldn't bother with aftermarket instrumentation.
If you really want accuracy, MPGuino is the way to go.
