TPS based boost control?

Not sure if it's limited to Autronic or not (I'd imagine MoTeC would be able
to do it as well), but it's an interesting feature. When I last used it, we'd
get the Autronic boost controller to keep the boost through the rev range,
then have it tail off slightly as gear changes approached (around 6000rpm).
This way, we could be a little more gentle on the gears.. I don't know what
it referenced, though - the car used a sole MAP sensor, however we had the
TPS sensor still hooked up. I'm not sure what we did with it's output, though.

Probably not fantasticly helpful in what we were doing (rallying), but a
nice idea nonetheless.
