Drivability issue... (turbocharger)

[EclipseGS-TuRbO]

Whats up guys! So lately Ive been having some problems with my car... Nothing to big (I hope)
So anyway. Mods I have done to my car.
-Apexi AFC (oldschool version)
-Bored 40"
-Stock 14b Turbo

Ya thats about it on that . This ones my daily driver so I don't have to much done to it.
The problem Im having lately seems like its the turbo . Under high boost when im heavy accelerating it gets up and goes and then it just cuts out and seems like it stutters. It doesnt completly give away but there is no power at all. It just kinda stops and stays where its at if that makes any sense... Its pretty hard to describe guys but hopefully someone out there has a similiar experience.
Ill try and add a video while im driving so you can hear what its doing if that helps. But any ideas would be great...

Sounds like fuel cut. Have you done any mods to increase boost pressure? BCS mod or boost controller? Why is it bored .040 over if there is no other mods to take advantage of the additional combustion chamber? What have you done on the SAFC?

Did you tune it correctly with the AFC? Also could be fuel cut, did u try replacing the fuel filter, or fuel pump? check the fuel pressure.

Well it was bored over from the previous owner.
Ive just had the safc sitting at zero since ive had it.
And for any mods to increase boost Ive done nothing. Right now all Im using this car for, for now is to get to school and back while im getting my talon running...

Havent really had time to get that done but I will check that out. As For tuning the AFC ive talked to people on here early in march and a lot of them told me as long as Im sitting at Zero on the AFC I should be fine for Daily Driving...

Yes as long as it is at zero it should be fine for DD. Just check the fuel pressure, cause it really sounds like fuel cut.

That's what I was thinking thanks for the tips guys

The fuel system has zero to do with fuel cut. Fuel cut is initiated by readings from the MAF. The ECU has no way to detect how much fuel is being sprayed.
