Default Hesitation at WOT CorkSport turbo

So I have what useems to be an intermittent issue.

At WOT around 4.5k to redline I get some hesitation and what sounds like some backfiring or sputtering from the exhaust .

Mods:
Built block. Manley pistons and rods. King bearings
CST4 turbo
Cs TMIC
CPE HPFP
Cs BCS
Cs BPV
Cs 3.5 bar map sensor
HTP 3.5 intake
Stock dp
UR race pipe
Stock cat back

The map I’m running is custom map that Will at PD did for the previous owner. However the car had a CS TBE with that tune. Looking at my logs i see fuel cutting to around 900 then shooting right back to 1800 2 lines after boost drops to like 4 psi then right back 18 psi. My logic is saying a massive intake with stock exhaust may be the issue.

I’m guessing I need a tune. Planning on getting one anyway. But I don’t want to pay for a tune if I my have an underlying issue. Oh. And I’m not going back to CS exhaust. The noise is just too much. That will be for sale here shortly. If any an can help me out it would be greatly appreciated.

I can post up a log if anyone wants to see it.
