fuel cut?

[OnlyNeed4]

ok, i have a big 16g, apexi n1 dp and exhaust, dejon intake pipe, and k&n filter. i hooked up my manual boost controller the other night and took it for a test drive. i get to around 3k rpms in 2nd gear and go wot, it takes off fast until i hit 5k rpms where i think i have fuel cut. the car accelerated fine until it felt like hitting a brick wall and 5k rpms. im new to dsm's, so im not sure, but was that fuel cut, or was i running too rich or what. Some people around town that drive dsm's told me i hit fuel cut, i want to get bigger injectors and pump, but they told me i can over-ride fuel cut some how until i get the money for my parts. Is it possible to over-ride fuel cut? how do i do it? all comments are appreciated

Sounds like fuel cut... just turn your boost down to around 14-15psi until you get a fuel pump and injectors and an safc. There is a fuel cut defenser, but not many people use it. I believe HKS makes it.

i have the boost controller turned all the way down, to minimal boost. i make 9 psi and it hits fuel cut at 5k rpms and a bunch of black smoke shoots out the exhaust. no matter where i set the boost conroller, it still hits fuel cut at only 9 psi, i should be able to run atleast 12 psi shouldnt i?

did you hack your maf yet ?? if not hack away that sounds like the problem and set the boost at 14-15 like herostar said... dont hack too much with no afc or fpr. your idle will suffer.

Did you do a boost leak test??? Had the same problem with my maft setup, would hit fuel cut at around 5k in 2nd gear, ended up having a huge boost leak.!!!

another thing that will help you out is colder plugs and new spark plug wires. Made a world of difference for me...
