2005 WRX cruise control

[bwyg]

Is it possible to tune the cruise control to make it more responsive?
Can an owner do it, or an independent garage? How about a dealer? And if
so, will a dealer do it?

My cruise control is lucky to be able to hold speed in a 5 mph range
going up and down moderate hills. My nasty old Ford Contour's cruise
control did much better, so I know it can be done. Both were 5 speed
manual transmissions over the same roads.

Wow. FWIW my 2004 STi's cruise holds it pretty much rock-steady, so
maybe you should indeed expect better from yours.

That doesn't sound right. My 03 OBS 5spd can do much better than that.
Perhaps you cruise at a relatively low RPM where your engine doesn't
have much available torque/power?

This has been discussed here before. My Ford products would go to full
throttle to maintain the exact speed at the cost of less fuel mileage. Every
time I went up a hill, it would downshift. My 2005 Forester XS speed varies
somewhere between 3~5 m.p.h. or 1~2 m.p.h. above or below the set speed. To
change this operation would require reprogramming the ECU. The last person
who complained here was told by his dealer this was normal operation for a
Subaru.
