You can fit a fuel cut defencer (FCD) to raise the fuel cut threshold,
but these units must be used with extreme care; FCD's simply fool
the ECU into thinking that boost levels are lower than they really by scaling
the output from turbo pressure sensor; whilst this allows for more boost,
the big downside is the ECU will also reduce the amount of fuel added to
the mixture, on a car such as the evo where the stock fuel pump is
marginal on modified cars, you will run lean very quickly. When fitting
an HKS FCD to bypass fuel cut on my evo5 (had fitted full exhaust and induction),
when I hooked up an ultra wide band lamda sensor, mixture was so
lean, if driven hard the we'd have destroyed the engine very quickly.
We fudged this by fitting a high flow fuel pump.

By the way, hitting fuel cut is not kind to your engine at all, if you
do hit fuel cut, get it looked at by a professional.
Best way to bypass fuel cut is with an aftermarket ECU or piggyback
ECU such as an HKS Fcon -they either raise fuel cut or remove it completely.
