5KTQW Low End Power

[spsherm@ibm.net]

We've got a couple of 5000CSTQW, which we use for mountain/city driving
at 5000-8000ft altitude, mostly at the upper end of that range. 

Overall they seem to be quite a good car for our purposes, but one thing
that still irks me about them (beyond the various repair/failure quirks
I am learning about) is the relative lack of low-end power.  

Yes I know that these are wagons, and therefore are carying around a bit
more metal, glass and whatever than the coupes.  And I know that we at a
relatively high altitude which hurts too.  But isn't there anything that
can be done move the effective RPM range with some torque down from the
3k+ range where it is now?

I mention this because several times I've read about the loss of power
these cars (turbos) have at higher altitudes.  And I was thinking that
someone up in the mountains must have worked out a tweak that helps...
I'm not after mod's that will get me a bunch more power up at the high
end (nice but not really what I need).  I'd even be willing to sacrifice
some of that high end power to bring it back down to the 2-3k rpm range.

Any ideas out there?
