Curious about Fuel Cut

[91LaSerTurBo3]

alright, well a couple times now ive been accelerating hard and then all of a sudden i feel a jerk, its not very violent, but you can definitley notice it. now ive heard things about fuel cut and such, and im just wondering whether fuel cut is related to too high of boost or what? because i know i was running no where near 16 psi, i hit 12 at most. but it doesnt seem like it's fuel cut from what ive hear, im just wondering if anyone can shed some light on what may be happening

When you hit fuel cut it feels like a brick wall. The car will die for a second and then the ecu will come back online , and everything will be normal. Is your car jerking or just shutting down,misfiring,etc. Please explain a little more
If it is jerking for just a split second its not fuel cut. Try a boost leak test,plugs,wires.

^^ not always man, i hit fuel cut cause for some reason my stock bcs will let my big 16g get to 18-20psi. it just kinda pops a little and jerks but not too bad.

I have had fuel cut and my car still does the jerk thing. Ok i run 15psi on a 16g when my car hit about 13 or 14psi it does it. I have a boost leak i thought it was from it but it is not fuel cutt. Fuel cut makes you think you just blew your car up. Well did me the first time i hit it.
