very small pw, injector can't working stable, bad idle, always after I depress throttle engine stopping.
may be engine running on semi-sequential mode?

I run 2500cc injectors all the time and i don`t have any problems. First of all go in to your fuelcut parameters, and raise your fuelcut from 1500rpm to 2000rpm and 1250rpm to 1800rpm. And overrun decay rate from 100% to 20%. Raise your ignition on 650rpm and 450rpm range.

play with your injector dead times
