[urq] Verification needed: 2.5bar 3B folk?!

[Chris Miller]

Been a while... My 3b ia III+ used stock fuel pressure regulator and
injectors.

I have heard that aan injectors require higher fuel rail pressure, think
the 7a one works.  You have stock injectors?

Hard to comment without knowing how it was chipped.
