Thats what I thought. My boost controller showed 1.35 kg/cm3 peak at one point. I did not get any boost cut. I guess the readout it must be inaccurate as I have a std ecu. The boost controller is a Blitz Dual SBC, have you had any experience with these over reading ?

It is possible to boost over fuel cut briefly

Do you have a Type S? The cut on them is
~1.33 so would be why 
I asked God for a bike, but I know God doesn't work that way.

This was just out of curiosity. I also run a boost guage which shows no more than 18 psi. The guage on the boost controller display appears to read above this. I just ignored the boost controller display and have been using my guage for setting the gain and ratio. I just wondered if the fuel cut was higher say at 19psi than the max recommended boost of 1.2 bar / 17.4 psi.
Cheers

i had boost cut at 19psi when on the rev3 ecu...

It all depends on the pressure sensor fitted to the car - there will be some variation between them, but 18-19psi is the right range IMO.
