Help: just replace the high performance fuel pump: car with WOT sound like choke off.....

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.

I got the Walbro similar with the XR4TIC used. However, my had a smaller inlet than the OEM....
will that cause problem? The Walbro I got is also 255lph High Performance It had the same size of inlet as outlet

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.
