The stock boost guage will rise to + when the Map sensor isnt connected, so im guessing its either fuked or theres a wiring problem.

wiring problem with map sensor id say. would explain the erratic boost light. check for broken wires or dirty contacts, trace the wires back as far as you can to be sure. someone like weejohn could tell you what voltage/resistance should be in those wires
