Thanks everyone for the input! Will report back soon.

The stock "accordian" air hose between the air filter and the throttle body horn collapses under WOT and cuts off acceleration right at the 4500 +/- RPM you spoke of. It's a common issue with 26+ yr old plastic.
I fixed mine with a aluminum sleeve liner for that hose. Marc Haibeck sells some wire hoops to be inserted at intervals along the length of the hose, and Jerry's Gaskets sells a replacement hose which also adds to the esthetics.
Get back 2 us!
