Who has expierenced the overboost cut-out?  What was the fix?  

My car expierences it sometimes in 3rd gear only around 6500 rpm.  No
problems in 1st or 2nd.  I have not been in 4th at 6500 rpm to test.
Car is modified with Garret T3/T4 hybrid, RS2 EM and software so boost
peaks around 23 psi to 6000 rpm then tapers to 18 by 7200.   If I do hit
the over boost cut-out, the car will continue to hit the over boost cut
out anytime the boost gets above 10 - 11 psi in any gear.  Once I
re-start the car all is well, no more overboost cut.   Any Ideas?
