there is an entire thread on the boost pressure too high on the prevost forum. i had the same problem on my 02 and found out that it actually doesnt even have sensor for high boost and that the error was false. but it did give me a check engine light and put me into safe mode. i pulled over, shut the engine on and off and it never came on again.

there is a tsb from detroit on it as well somewhere.

i guess it depends on which series 60 engine setup you have

but a very good comment and something to be aware of.
