Default fuel cut question, need advice,

here is the story and what im wondering abought

i have all the goodies and puting the 740s and 255 pump on this weekend i am runing a pe 1820 turbo upgrade set at 14 psi at the moment, cause im runing stock injectors and pump

i am also runing the super AFC at the moment

my questions is

whene i put the injectors and pump i should be able to increase the boost to say around 19-20 psi with no fuel cut? sense it is geting more fuel, or is fuel cut set a pre determined boost number?

also fuel cut reads the MAF reading and O/2 reading to determine whene its geting leaned out? or something else?

will i still hit fuel fut with injectors and pump?

yes i know i should get a utec but money is verry tight right now and there is no exuse for cuting corners but i am, i am hoping the AFC will do in the mean time,

im using a freinds wide band o/2 sensor this weekend also to help make shure fuel is on the right seting but if it still hit fuel cut at 15 psi im screwed,

thanks for your time and reading this

without some kind of MAP clamp or fuel/boost cut defender you will hit fuel cut at 17 or so psi of boost.

The fuel cut is programmed into the ECU. It is seperate from the fueling. When I had my reflash done I had it moved up to 25 psi.
