Does this look like boost cut?

See the Datalog

it looks like fuel is all over the place but boost cut it is not....u are not making high boost when it dropps off

[Lymerock]

cant see the log too clearly, but that fuel looks like poop
any idea what your a/f when its happening?

It looks like your fuel pump is failing.

when I had boost cut it was a quick cut and then boost was right back to where it was (maybe a little lower) but nothing like that. new fuel pump

waiting on internals kit from PG. I never had a problem until TMIC was installed. AFRs are rich all around. Here is another datalog with a shift from 3-4

That's fuel cut. I can't read the numbers but that looks suspiciously like mine before I upgraded.

Again With The Fuel Cut

kingpin after you upgrade it did it resolve the fuel cut issue completely?? rate the solution from 1-10 10being fixing the solution completely.

I don't get the drop in pressure on the datalogs or the hesitation after the upgrade so I would say it's a 10/10.

I'm seeing a lot of different opinions on these things here these days. My fuel issues where more of a sputtering/hesitation. My boost cut was like hitting a wall, violent jerk, which I fixed with the MAP clamp.

damn...i dont know how to explain it furthur...

if i punch it to the floor at 3500rpm i get a sputtering then it picks up at higher rpms consistently. then when i change gears sputtering begins again (accompanied with a backfire) then picks up when im around 5000 rpm...it last abuot 1sec to 1.5 sec. damn dashhawk needs to get here fast.

That's exactly what happened to me. When I started down low I got the hesitation and watched the Fuel PSI plummet to 400. If I started from above 4000rpm or so it wouldn't happen. I don't think the CDFP could keep up with the long WOT run.

I'm 100% sure that the CDFP upgrade will fix you since it fixed me with the same symptoms. Our mods aren't far apart either.
