Fuel cut...I'm surprised you can go that high on boost 
Check your ECU codes to be sure...code 34 is a turbo overboost (i.e. fuel cut)

yeah, even w/ the neo, you can only tune BACK fuel cut, it will still be there. and indication on what your AFR is at 22psi? before/during/after the jerking? what gear and what RPM range are you in at that point? little more info regarding the issue will help pin point. But yeah, I'm surprised you're hitting 22psi at all w/o a modified ECU, FCD, or MAFT.
fuel cut.. the stock ecu can only take so much
like things already said, the modds u have only raise fuel cut they dont eleminate it
ive heard the fcd is the quick way to pop your motor, fuel cuts there for a reason.

i think thats your problem. fuel cut will still be their tho
the lem afm is 25% larger than the stock afm i believe (or something like that)

its fuel cut we keep telling you what it is
if u dont want the advise dont ask for it
do some research and you should find out why

if you got the lex afm then u can raise the fuel cut a little more
so u could probably push a few more pounds
