Sounds like you may be going lean at higher throttle. Can you monitor your
O2 sensor in any way?
WOT switch tends to activate at 60% or so throttle position, and is easy to
test with an ohm meter and the engine off. Like you said, unlikely.
Not sure what you mean by "Frequency valve set to apprx 43-50% range". Is
this set statically, or is this what you are monitoring when you are at WOT?
