Idle RPM on Jet Engines

I've looked in both the "aircraft" file and the ".air" file and cannot find anyplace to set the idle RPM on Jet Engines in FS 2k2.
I've downloaded Ray Lopez's RLQF-86 and the engine idles at 70% rpm and I want to set it down to something like 40%.
I don't think this is a simulator thing because other jets have idle rpm in that vicinity (about 40%).
Anybody know the answer ?
