fuel cut problems

[DC Walker]

I just installed a 255 lph fuel fump on my 1998 240sx with s15 motor and it is now having a fuel cut at a lower rmp than before and is there a way to bump up my stock regulator to help

We would need to know a little more about your setup to be of any help. How much boost are you running that you have fuel cut. What bolt ons do you have. What are you using for engine management.

well i guess that would help sorry about that i have a 1998 240sx with the s15 motor and six speed trans. the bolt ons are a blitzs DD blow off valve, greddy fm intercooler, ceramic turbo manifold not sure what kind, 3" apexi exhaust all the way back with test pipe, apexi safc II engine managment, greddy turbo timer, and boost controller and i am running at 11 pounds of boost. i have a greddy intake but have not installed it yet cause i am still waiting on my z32 maf to come in. but the reason i installed the pump is cause i am running lean i think for the reason is my spark plugs are burning real white and my turbo manifold is turning crazy purple colors. do yall think it might be my safc II and how would i correct that and my fuel cut is happing around 4300rpm 5th gear and sixth around 4000 . thanks and sorry for not giving more info before.
