Fuel cut and misfiring!!

[GsXdSmKingGsX]

Ok so my problem is that if i go over 4k rpm's in any gear sometimes i will hit fuel cut. I have a stock T25 turbo running at 14 psi, stock fuel system, brand new NGK BRP7ES plugs and Accel 8mm wiring. Also my freakin plug wiring adapters barely fit those plugs and they are all different lenghts.

Also in the top gears i get a hesitation and it might be misfiring but like i said the wiring and plugs are new so im way confused. Help me out..

If the wires barely fit, are you sure you are not getting a spark cut, instead of a fuel cut?

Did you have this problem before the plugs and wires?

I would check on just a stock set of replacement wires from Advance Auto Parts, and throw them on their for shits and giggles, and see how your car runs.

Why are you running 7's with a stock turbo? too hot for your 6's?
Gap them at .28 or if they are right now, I would go down to .25 and see if that remedies it. Your plug connection isn't secure? Try to crimp them for a better fit.

I just noticed your gigantic everstart battery, is that made for a 2g? that looks like it hits the hood!

That engine shot is actually from my GSX which i crashed. But anyways im running 7's because they run alot cooler.

And also they're gapped at .026 abd yes i had the misfiring problem before the plugs and wires which is why i replaced them but the fuel cut is a brand new problem

First thing to do when you have fuel cut is.......... Boost Leak Test!
