Overboost cutout (was cutout/stumble on an MC engine)

[Swann, Benjamin R. (BSWANN)]

[At 3/4 to full throttle and between 3500 and
5000 rpm the engine will cutout for less than 1 second
and then recover like nothing is wrong. ] 

Jim,

You are experiencing the fuel pump cutout the ECU provides when greater than
1.5 Bar is detected.

Most likely culprit is the lower wastegate hose, but this is a good time to
check all the hoses going to and from turbo and wastegate.

Don't be deceived by "good" looking hoses.  I had one that looked ok, but
had disentegrated below the cloth.  This cutout is an inevitable experience
that occurs with these cars.

Once you get that fixed, you will likely be missing the extra boost you were
experiencing.

I have a chip for 1.8 BAR and other inexpensive modifications outlined in:
