How to eliminate fuel cut in piggyback mode

[felipeandrest205]

Hello there, I raise up the boost to 1.2bar in a Celica ST205 and it hit the fuel cut, could I eliminate with a proper fuel tune or I need the FIT mode?
I havent try tuning the fuel map
Greetings!

You can set an upper limit for the MAF or MAP signal to avoid fuel cut, but then your ECU is going blind past that point, so use it with caution.
