Tom: Sorry but with that attitude, there is no reason to ask your question here. You apparently know the answer already. LOL.

However, did you know that when the Michelin Man cross-over to intercooler hose split opens up and dumps a massive amount of air, the ECU freaks out and goes into limp mode? Turning the key off and on likely resets the ECU back to non-limp mode and the process starts over again.

But please, persist in ignoring good advice and DO NOT check for boost leaks.

Thanks for the advice!

First thought was leaks, but I can't find any.

My ECU is acting oddly, but just on occasion. I got 20-30 ok runs between ECU failures--boosting perfect (I have a gauge)--overboost works fine.

When it goes into this mode, it shuts off as in ignition shut off when I floor it.

At part-throttle runs normal.

But when I re-start it it is fine & no boost loss--runs great.

It also occasionally goes to a 2100 RPM "idle" when I start it. Again if I re-start, it is normal again.

I am in the mode of waiting for these faults to become more regular.

IF you haven't done a proper boost leak test as per my Boost Leak Post, i.e. complete intake and PCV system under say 15-20 psig, with soapy water, I remain skeptical that you don't have a boost leak.

Sorry. Good luck.
