S80 hitting fuel cut when WOT
 

I recently changed out one of my ignition coils on my 99 T6 which means I had to take off the intake/plastic turbo pipes.
I double checked and made sure everything is connected and connected tight, but for some reason when I use full throttle i hit fuel cut around 3k rpms.
If I don't use full accel, i can take up the RPMs no problem.
Has anyone had a problem like this before? Is there a possibility i switched up some vacuum hoses when I took them off?

Double check your vacuum lines but also look around on this forum. For me, this situation got worse and was because my fuel pump was failing. That was also sudden.

You will only hit fuel cutoff if you are over boosting by way to much.
