Fpr and maft

[GSX93DSM]

Need a little help. I bought a 90 tsi and it has an fpr and a gm maft. I just need to know what the fuel pressure is or get me close to where I need to be.

20g
550 injectors,
255 fuel pump,
gm maft,

I have mine at 43 psi

I looked at the base setting for the injectors and is set at 0 which should be set at base C for 550. I just didn't know where the fpr pressure should be

I set mine at 43 on my afpr.

Thanks, I haven't checked yet but the guy told me it was set at 50psi.

Yes check it out and youll know for sure, and adjust as needed.

1g stock fuel presure is 37.6, I would think 550 injectors would be to small to reach the full potential of a 20g

Im only gonna run the 550's to break in the engine. I planned on upgrading to an hx35 or 40 late on also. I will probably just buy some 1050's or 1150's.
