fuel cut load with 3.5map

any idea how to set this for no load fuel cut?max settings is 35.12 i want to run 36-38 psi but dont want to use a 5bar map since it dont have a 4 bar option.in other ecus i have run 44psi with a 3bar map with a lot of success for years, just tweaking with the 30psi range in the fuel cells.i know is not the best option but works for me. Any idea?

If you use 3,5BAR sensor it means you have 3,5BAR absolute, so it is aprox 2,5BAR relative to athmospherical preasure. And 2,5BAR is aprox 35-36PSI. So you cant set Boost Cut to something higher, because you would be out of scale.

Depending upon what aem version you are running I believe you can turn it off by setting it to -14.69

Sorry, but how do you want run off-scale ? How should your ecu know how much fuel or ign you need in this case ?
Dont do something stupid, 5BAR map is not so expensive
