Hitting Boost Cut On MBC

So I am currently using a Hallman Pro RX Manual Boost Controller, and I am hitting boost cut everytime I exceed something around 320 load
This is what my boost limit table looks like. Why are these values in percentage, is there anyway I can change them to load?
Note: My car has only a MAF sensor and no MAP sensor

Tariq... if you have not played around with your maf scaling then 320 load is well over 2 bar

the values you see there are load values... 230 translates to something like 1.3 or 1.4 bar...

thats why why you are hitting boost cut...

Also, if those are load values, how come I am hitting the cut at 320 rather than 230?

Because you got fuel cut.
You'll see it on a data log.
