MAP Pressure Fluctuates
I know this probably belongs in the scan and tune section but nobody responds in there. As title says, I am having an issue at WOT my map pressure is fluctuating, at some points it gets down to 90KPA. The car is a head and cam car, Dart 205's, 224/230 cam. Any ideas?

Sounds like an intake restriction. Either the intake itself is not feeding the engine fast enough or your filter/intake tract is at fault. If as the RPM climbs up near redline you are observing a steady drop, you are building vacuum in the intake.
