Default Sounds like your going to need an adjustable FPR

to lower the fuel pressure down since your getting way to much fuel now. Your car is choking because your running rich. If you have a vag you want to check the 02 sensor readings at WOT.

Default For one X4RTIC has a 2 liter now with a T3/T4.

Did he do this with the old motor and K03?

Default if you push too much pressure through an FPR you can destroy them..

Same thing happens with folks that put the CIS pumps on digifant vw cars. Will eventually ruin the FPR due to the excessive pressure.

It's a simple spring tensioner diaphragm, if you push 100psi through the fpr which was only designed to take 43-63psi it will eventually break.
