wierd tension on the throttle cable somewhere, possibly.

Unrelated but, With an rtek 1.7 isnt 720cc primarys and 750cc 2ndaries too much fuel? I thought that ecu was calibrated for 55o primary and 720cc secondaries.

not a boost leak from the piping, but a vacum leak somewhere..

Either a snagged throttle cable (check for binding) or more likely you blew a vac hose off under boost and now have a really big vac leak. The leak will be after the throttle body, so look for hoses hooked to the upper or lower intake manifolds.
