Fuel Cut/boost Cut?

[SL1D1N]

Hello my car is a R33 series 1

T2871r

Frontmount

full exhaust

Safc I

Profec B EBC (turned off untill tune) boost spikes to about 12psi

Stock ecu, injectors and afm

i recently replaced the coils which fixed my missfire. The other day i was driving it and under full load on boost felt like it started to do it again. Except this time it would fully stop for a split second then go again, then stop, and go again. Happens at higher revs and when my foot is to the boards. Car is untuned getting a 040 soon then will get it tuned. i have heard of fuel cuts on these maybe thats it??

Any ideas

cheers

Firstly that link didnt work, and im not running big boost, nor is the turbo that much bigger than my stock one. I undersatnd that its those things however i know people making heaps more power than mine on the same stock set up. I need to know wat is actually causing this to happen. I dont just want to throw parts at it.

there is no boost cut

Its a flow cut, the more air, the more damage can be caused, so the ECU protects the engine.

You have a factory ECU and AFM which are guaranteed to be the problem.

If that link didn;t work, then at the top right hand corner, there is a button called "search", I suggest you use it because this problem is covered about once a day.
