Fuel cut

[Graveshaker]

Hello all, I recently got back into the speed3 platform after nine years of owning my first speed3. 2008 speed3, 138,000 miles the car is 100% stock but I'm able to tell that it did have modications to the exhaust and intake at one point. It's evident that the HPFP has been taken apart because of the zip tie to catch the fuel line bolt and obvious marks on the torx screws. I'm unsure if the internals have been returned to stock however.
My issue is a violent fuel cut or spark cut in fourth gear at near full throttle using two different maps. One was the Cobb stage 1 that was on the car upon my purchase and later the stage zero to mimic stock tune.

I did my best to check hoses and such when I took off the battery tray and stock intake. I did notice that the intake to turbo was very loose and easily fell off when barely touched. I initially assumed that this was the culprit and didn't bother checking spark plug gap (I know stupid) and put everything back together to realize I still had the issue. One other thing I did observe was oil pooling on top of trans directly beneath the HPFP. I'm assuming a pinched o-ring. Enclosed is a data log, any help would be greatly appreciated. datalog15.csv
