at what RPM are the secondaries supposed to open? Mine open at about 3500-3750. Just seems a tad high for me. Is this correct? would a mod chip change this?

My 1999 SVT Contour sales brochure says 3400 rpm for full throttle runs and 3900 rpm otherwise.
Dunno about the regular Duratecs. I think it's a fixed rpm somewhere around 3500 rpm.

I've got a 98 SE, regular Duratec. You can feel it when the secondaries kick in, and it does vary by how much throttle I'm giving it. 3400/3900 seems about right....

3400rpm at WOT, varies at any other throttle point (4000-5500).

What I have understood is 3400 RPM at WOT amd 4000 RPM otherwise. This seems to be what I feel when I drive as well.
One of the changes a superchip makes is more agressive secondary opening. I remember Ray McNary saying that this is what he probably liked most about his Superchip.

Someone on NECO rigged up a small light to the IMRC and found it engages from between 4000 and 5500 if you're at less than WOT, but I could be wrong.

I always thought that they were at 3750. That's when I can hear them and feel the pull of the car more...
