Limit of the boost level On stock ecu

[juan jz]

I need help, I'm trying to set up my cars boost level so I can take it in to get tuned, I want to know the limit of stock ecu before it hits fuel cut. I'm using safc II

around 13-14psi iirc

right under fuel cut, it can be different on different elevations and how cold or hot it is that day. My friend has a 57 trim turbo on the stock injectors and hits fuel cut around 9 psi on a hot day.

are you on stock injectors? with my fuel pressure cranked way up and a tune with a safc2 i was able to run 18 psi without a problem for dyno numbers

I'm running 440, I started cranking up the boost to 14psi but it would hit fuel cut at full throttle, so I have it at 12 and is pulling hard all the way through, I'm going to start looking into upgrading ecu, what do u guys suggest? Aem would obvious be the way to go but I'm leaning toward mines ecu since I'm on low budget at the moment

would you guys recomend installing a HKS Fuel Cut defensor to boost up higher on stock ecu,
