I'm not sure about what action  the ecu takes because of high IM temp 
(SJM's web site explains that, though), but your question got me 
thinking about that notorious boost-killer, the defective MFTS. The 
latter-day crop of 3-pin sensors can be insidious when they fail 
because that often does not affect the temp-gauge reading. Have you 
disconnected your MFTS to check if there's any gain in boost? A good 
MFTS, when disconnected, does not reduce the boost, but disconnecting 
a bad MFTS will generally restore lost boost.
