I think there's also an anti-surge modification described in the service manual. As I recall, it involves adding a switchover valve into the line which feeds the ALDA. When cruise is activated, the switchover valve changes the vacuum/boost path such that it passes through a restrictive orifice and/or surge damper. The effect is to delay throttle response - the ALDA doesn't add or remove fuel so quickly, smoothing things out.

I've an '87 300TDT and don't particularly have any complaints about the cruise. Well, it does drop out once in a while - guess I should lube the throttle linkage. Of course, it's so durn flat here in Texas the throttle never gets moved to maintain speed anyway...
