One of the HKS boost controllers has the ability to control boost versus RPM
and versus throttle position. I think it is the Pro model. It isn't cheap -
I think it retails for something like $1200. The HKS controllers seem to
work very well.

Limit Engineering also makes a boost controller that has a TPS input (and
also can vary boost versus RPM). I think they just call it a Turbo
controller. It also has auxilliary injector control capabilities.

I think one of the Apex'i (spelling?) models might also have this feature (I
think you can have speed or TPS on the Apex'i). I have never used this boost
controller though (just saw it at SEMA and in the magazines).
